Except for regulations on commerce, control of their currency and a removal of democratic elections for leaders right?

>>regulations on commerce

Which ones exactly, and please be specific.

>>control of their currency

I mean, no one was forced to take the euro? The countries that did it agreed to it at their own state level first. And there are many countries that have agreed to it initially and then changed their minds and didn't do it. Yeah sounds like loss of sovereignty to me.

>>a removal of democratic elections for leaders

I'm sorry I think I must have been sleeping in the last 30 years - when did that happen, exactly?
