The EC pushes through controversial decisions, that are not controversial between states... the bar is generally something high in this regard.
National Governments get a buffer between them and discontented citizens, because "it's the EU." There is also a lot of pressure to conform to EC "consensus," parties/individuals that want to be seen as government material.
EC totally discounts digital privacy especially privacy from state actors and there is corruption, carve out a and such. I disagree with a lot of their agreements. I agree that they make far too many laws and are way too bureaucratic but....
EP is a shitshow on another level. It's literally the star wars senate. Endless factions, recreational politics. No about to act in a way that might result in anything but show. It's trump, but boring.
National governments also don't lack in corruption. Politics sucks.
IMO, what is badly missing is an active electorate. Civil society. There needs to be an organized, pro-freedom movement. ATM, EC is taking advice from tech industry,dirty insiders and spooks. No one speaks for "The Cause" because, to paraphrase americans... "When I need to speak to Europe's digital freedom people, who do I call?"
