Two points:
1. Regarding withdrawals from two locations 'simultaneously' by a depositor of a particular bank: Although I'm not certain that the Star Kingdom still uses physical money (coins, notes, holocubes etc.) wouldn't the withdrawer need to be physically present to make a physical withdrawal?
I can imagine a system where a business at a particular location (vendor, supplier, retail shop, merchant ship purser) will only accept electronic funds transfers from the local bank branches (e.g. MWJ Branch of Bank of Manticore, or Banco Madrid etc.)
So a depositor would have an account with the bank's central location (clearinghouse) and would then need to transfer funds to 'spending' or 'chequing' accounts at specific locations of the bank (e.g. Sphinx Branch, MWJ Branch, Medusa Branch).
Another interesting outcome is that because of nano-level manufacturing capability most of the items used as money in modern times would be a breeze to forge.
Money would either be in the form of certified letters of claim representing funds transfers over interstellar distances encrypted using one-time-pads (to stop the bearers from writing extra zeros on the cheque, for example). The recipient branch specified on the letter of claim would pay out (or transfer funds to) the first person to arrive bearing a copy with a particular serial number. This would be because it would be easy to duplicate these letters.
To verify the amount inside a certified letter, you would need to take it to a branch (transmitting a copy over any channel would be folly).
Unless the transactions take place between two parties with complete trust then a copy of a letter of claim cannot be transferred between parties (because of the duplication problem).
This would limit the scope of activity of an old fashioned free trading merchant ship, either they would have to operate within an area of operation where they have good credit with a particular bank and/or good reputation with trading partners. Or they would have to periodically return to the central clearinghouse system (as their operating capital would slowly become tied up in illiquid letters of claim). The other possibility is to barter with goods and/or precious elements.
Looking at this system it is clear that commercial advantage would lean extremely heavily in favour of large trading cartels and corporations that can integrate information over large areas and best arbitrage differences in values of goods and currencies. Furthermore larger more reputable traders such as Hauptmann Cartel or Jessyk Combine would be trusted with transactions that smaller 'fly-by-night' operators would not be.
Keep in mind that a perfectly honest and trustworthy merchant showing up in a system where he or she doesn't have a longstanding reputation and/or existing relationship with the bank(s) would only be able to sell and/or barter. Depending on the value of the product they might not even be trusted with haulage of third party goods. The Galaxy is a big place and fraud would be extremely difficult to recoup.
Banks would also need their own fleet of courier ships to shuttle all the One-time-pad (OTP) information out from their central clearinghouse and square up accounts and transactions with the interstellar branches.
A bank robbery would not involve stealing bags of gold coins, it would just require the robber to get a copy of some of the OTP information. As long as they have some basic knowledge of how transactions are written/formatted by that bank it would be the equivalent of stealing blank money orders - they would be able to write out their own letters of claim and take it to the central bank to get paid out. The degree of security on those banks would need to be as close to absolute as humanly and electronically possible. I imagine that the server where the OTP information is stored would by physically separated from the rest of the bank's network as well as the planetary nets etc. Output would be through one-way channels and full access only available in a room protected by mission-impossible style security - including a self destruct mechanism.
2. The PRH had serious economic problems.
Quoting from Ch.7 of Flag in Exile:
"Pierre couldn't have accomplished all he had without the rot spreading from the Legislaturalists' policies, yet the very thing which had made their overthrow possible also made it all but impossible to fundamentally change the system they'd spent two centuries building. They'd created a vast, permanently unemployed underclass, dependent upon the Republic's stupendous welfare machine for its very existence, and in so doing, they'd sown the seeds of their own destruction.
No one could place two-thirds of a world's population on the Dole and keep them there forever without the entire system crashing . . . but how in hell did one get them off the Dole? "
with additional emphasis in bold.
Coupled with the inferior education standards of the PRH you can see why their military production output might be somewhat depressed. (Don't forget to factor in the inefficiencies of a command economy).
What really amazes me is Grayson. Their prewar workforce participation rate would have been around 15% of total population (25% are male, minus those who are too young or too old to work). Even accounting for the effect of women in homemaking, child raising (and education?) and possibly agriculture (working the family farm?) this is still a very small percentage when you consider the problems imposed by planetary conditions.
Even if you assume that one orbital farm would support 10,000 people, assuming 2/3rds of the food came from orbit and a population of 3 billion, that would require 200,000 orbital farms. I imagine something like that would show up in the night sky (or even daytime sky?) as a BELT.
Now there was even some mention of cattle in orbital farms. I imagine that those cattle would only be available to the extremely rich. This is because of the inefficiencies of raising cattle compared to the equivalent crop yield you could achieve using the same amount of 'land'.

http://www.farmlandlp.com/2012/01/one-a ... -a-person/Now assuming that year-round growing season and 24-hour sunlight both increase agricultural productivity twofold, this means that the space farm needs about 2500 acres of surface area (growing area) which is pressurised and sunlit (or lit with UV lamps internally such as a hydroponic system).
Plugging this back into the figures above this means that a population segment of 15,000 people (which may have around 2,250 working males - don't forget the low life expectancy) needs to support not only the regular planet-side economy but also a space farm of 2,500 acres growing surface AND the space transport to bring purified raw inputs up (water, air, fertilisers etc.) and food produce down.
Now you can scale the size of the orbital farms up and down if you wish, but the amount of surface area required still varies linearly with population.
Maybe this is doable, but now that I've run through the numbers this does stretch my suspension of disbelief. It certainly would not be possible
at all without counter-grav technology.
But if the Graysons were able to keep this house of cards up before the Alliance then I imagine they could certainly build a modern space fleet in a couple of decades once they weren't working with both hands tied behind their backs. Don't forget a good number of their SD hulls were sold to them at scrap prices by the Highridge government.
