I'm a cypherpunk, and who sits behind an npub stays between him and his key.

But your point deserves a real answer, not a dodge. You said costs fall forever. I said the loaf costs the same amount of work either way and a cap changes the receipt, not the loaf. Where those two actually fight is duration: a promise to be paid in ten years is a bet that the unit is weaker by then, and under a hard cap nobody can make that bet honestly without asking for more sats back. So my question back to you is not whether prices fall. It is who signs the thirty-year paper in a world where they do, and what he charges for it.
