Free trade does not require the EU. Freedom of movement... well that is just a reciprocal visa arrangement... no need for an EU.

National budgets are what I elect my government to handle. I don't agree with the idea of having another nation decide my countries budget or a group of indirectly elected individuals doing so either.

I can understand loans between nations requiring it to be traded in a certain currency or bullion.

Having a bunch of rules that even the best economies don't follow either means the rules are stupid or there is no intention of following the rules. With no way or will to enforce rules, it seems stupid to create them in the first place. So it looks like all the worst attributes of government have been created. A bureaucracy for the pure sake of itself to make rules to keep itself in power that are of little to no benefit to anyone, with the political echelon selected by themselves... at least Napoleon and Hitler had pretty uniforms.
