if it ever comes that far, the current owners of bitcoin can only gain goods by spending their bitcoins.
unlike the current wealthy elite, they can not just print more money.
eventually even the richest bitcoiners will go broke if they keep spending their bitcoins.
well no you buy assets where people pay you in BTC for them, BTC is not destroyed when you send it its just cycles through the system.
BTC can only be lost from the system due loss of private keys, or maybe dust issues, the latter may be soluble
