How much POB are we talking about? First of all why would we entertain the idea of permanently removing BTC from the ecosystem? Today's change can be next decade's car (or for you bears that want to start a fight for no reason, it could also be next decade's trash).
That's the same argument Bitcoin detractors use against spending any Bitcoin ever. Why would you ever spend any BTC if it may be more valuable tomorrow?
Yeah, why not something like this?
It's more complicated, maybe? Proof of burn is
charitably donating the value to all BTC holders.
