The raison d'etre for these kind of institutions is precisely to centralise power. So that matters of wider community importance can be agreed upon collectively and standardised. And we absolutely do have issues that need to be solved at a continental level. The problem is that sometimes those institutions overreach into areas that should be handled at a lower level. Arguably the British Parliament is more guilty of this than the EU and has control of things that are much more important to everyday life.
