As for the recruitment fair idea, I don't really see it tied to the cited capital issues. Those are interesting mechanics idea, but it's on the whole mostly a tweak on the current system, where a capital on the border helps reduce the refit cycle but intentionally placing it there is against the rules.
The point is that only being able to recruit in the capital
is a gameplay balance decision, and as such, circumventing it by moving your capital (or seceding)
specifically for that reason has no IC justification. It is purely an attempt to circumvent a deliberate balance decision.
If we change the decision on balance, then there's no longer a reason to restrict secessions and capital moves, because there's no longer a recruitment benefit to doing them.
