I just wanted to write "fully agree", but always beware of the extremes. Germany has learned the "don't give too much data to a central government" and has separated institutions and states.
The price is that we as citizens often have to give similar information to different institutions - and that can suck! "can't they just get the info from xyz". But that's the other side of the coin.
Everything comes by a price.
(this is not a "we must centralise" - just a "everything has a price")
