"Boo EU bad" has become a meme already. Yawn
The UK is the extreme example of this: for a decade, their EP contingent has had a massive number of euroskeptic politicians who never managed to win more than a single seat in the British Parliament. Brexit proved that Strasbourg was actually more representative than Westminster.
The definition of federal: "Of or constituting a form of government in which power is distributed between a central authority and a number of constituent territorial units"
OP is suggesting a more decentralized EU, not a "bigger leviathan"
