You say "centralization" but EU and NATO countries gain massive amounts of power and strength from banding together. Tiny Croatia has no hope of protecting itself militarily or economically compared to being in those institutions. In each case countries are eager to join because they have so many benefits. Your claims about plutocrats work in the opposite direction: corruption and influence is worse, and the rule of law is less effective when a country is smaller.
