“The only thing more scarce than bitcoin is time.” Every minute that passes is one you don’t get back. Bitcoin can store economic energy, but it can’t store time. FIRE buys back that resource before it runs out.

Longevity Escape Velocity (LEV) flips the premise. Medical advances would extend life by more than one year for every year that passes. If your timeline stretches from 80 years to 300—or indefinitely—a retirement system built around a 20- to 30-year payout window no longer fits.

FIRE still matters, but “retire early” starts to look more like “re-tire”: put on new tread and reinvent yourself as your goals evolve. Low time preference becomes even more valuable when you’re planning for centuries instead of decades.

Your financial foundation also has to survive radical change. Fiat currencies will fail, institutions will falter, and systems will reset. Bitcoin operates without a government, central bank, or corporate board. Its transparent rules are enforced through voluntary consensus and built around perfect scarcity.

If you’re building for an indefinite life, durability becomes the test for both FIRE and money.
