I could agree with you if it was only talents and magic that were affected. But sharonian weaponry (no talent or magic involved) is also affected. So why would the Sharonian rifle not function if there was a layer of continuously operating physical laws in place. Somehow a part of the physical laws changed that didn't permit the rifle to function until a Sharonian tried it, and then it didn't function properly. The rifle only functioned at full power when Gadrial came up with a pseudo magical explanation for its function. An explanation that she admitted turned what the Arcanans knew of physics on its head.
The part about Jathmar and Gadrial being able to fire the rifle, are both important, I'm just not sure what it means yet. A few of guesses:
1. Gadrial may have used magic to supplement the firing of the weapon (we don't see a any one else try to fire it after she gives her explanation). She may not have even known she was doing it.
2. Jathmar (and any other Sharonian) may have an area around them in which their home physics may partially function, regardless of where they are.
3. A sentient being may be altering the physics around them by the simple expectation in the alterations. If so then a world may end up assuming an average if its inhabitants beliefs in physics. That average then becomes the rule (regardless of apparent inconsistencies to us), and then are taught as fact, cementing the physics in place. This could explain why we have legends of magic and dragons (people used to believe in it).
