NEO Surveyor (2027-2032) will close the city-killer (140m-1km) detection gap from 44% to 2/3. However, planetary defense has fundamental scope limitations: (1) Long-period comets provide only weeks-to-months warning — insufficient for kinetic deflection deployment; (2) Gamma-ray bursts have no warning and no deflection mechanism; (3) Supervolcanism (Yellowstone/Toba-scale) has no deflection technology and uncertain timescales; (4) Anthropogenic catastrophe (nuclear war, engineered pandemic, AI misalignment) represents the most probable near-term extinction-level risks but has no deflection mechanism. The multiplanetary expansion argument is WEAKEST for detectable asteroid threats where planetary defense is effective, and STRONGEST for anthropogenic and undetectable/undeflectable risks where geographic distribution is the only known mitigation. This creates a complementary rather than competitive relationship: planetary defense handles impact-detectable threats; multiplanetary expansion addresses everything else.
