How realistic is this though? Getting elected to Congress usually means having some other prior government experience, or your opponents attack you with "why would you give this person responsibility at a congressional level if they've never even worked in local politics?" Not to mention you need name recognition, a history in government that people can use to understand your values as acted, relationships in government to accomplish anything.
As I get older it seems that liberal democracy basically requires career bureaucrats to function. I'm very open to discussing other ways of organizing society, but if we're gonna do liberal democracy, seems this is the way.
