Americans aren't used banking systems that work.
The only large exception I am aware of is dispensaries because banks don’t want potential drug money laundering charges.
And the problem with good governments (and fair elections and other properties of decent democracies) is that they can accidentally let bad actors in (populism is one helluva drug for the masses), and bad actors may attempt to undermine the institutions, turning democracies into kleptocracies and dictatorships if they succeed.
Then all those safeguards in the name of all that's good become perfect tools for abuse in the name of all the control over whoever dares to oppose the established order.
I'm pretty sure Europeans have heard of Hitler and Stalin and their ilk.
