You can't "prove" that Earth's gold supply won't increase with asteroid mining either. We can disagree on the relative difficulty of asteroid mining vs. changing Bitcoin's consensus rules, but you must at least concede that they are both possible.

Right... No matter how many people wish it to be so, the amount of gold on the planet cannot be arbitrarily increased, instead, you'd have to go to extremes likes mining astroids in space, a feat of engineering that is only possible in theory.

Mining asteroids is quite possible in practice. In fact we've already taken material from asteroids and returned it to Earth. The only question is how long it will take for the technology to advance enough for profitability; there are no fundamental issues preventing it. It really seems inevitable assuming no civilization-ending disasters. And it can increase Earth's gold supply arbitrarily up to many times the current supply. And it only takes one company to do it. Anyway, if our only disagreement is on the relative feasibility of changing Bitcoin consensus vs. asteroid mining, I'm happy to continue to disagree with you on that.
