My point is that sovereignty over issuing currency is synonymous with sovereignty in general.
What you're saying is that you're glad the government in Italy is more like a state, than a nation.
That's a fine point of view, but it implies that your country is incapable of self-governance. Do you think that's the case?
It should also be noted that I don't think there is any issue with economic federation, only that there is economic federation without political federation. As such, you have a monetary body whose power exceeds any political authority. However monetary policy can't truly operate in the absence of fiscal policy, so what you really have is a bank as your federal government.
