>Nationalism is the problem behind that, not the solution for it

I dont think nationalism plays into this. If we didnt have a supra national body with that kind of power we wouldnt have article 13. Quite a few of the regulations where proposed on national levels first, like the link tax in Germany, and rejected there. It was similar with providers being forced to collect your browsing history. The constitutional court ruled it illegal in Germany and it was then proposed via the EU and enacted there.

I see absolutely no reason to enforce any regulation that is not aimed at enabling a united market across the member states. The EU is an economic union not a United States of Europe.
