It doesn't matter with any currency. You don't price things by how many dollars exist. You price things at what people will pay. If the billions weren't being spent, its about the same as if they're never spent.

Printing money and giving it away causes inflation because people can use it to buy things but having money printed but locked away does nothing. If this money was locked up then its not much of a change.

“We” can arbitrarily print more Bitcoin or dollars. In either case you just need consensus among the correct group of people.

Technically true, but the big difference is that if someone hard forks bitcoin to start printing more, holders will see their coins fork with the chains. You'll have both the old, hard money and the new diluted money, and the market will decide which one is more valuable. This doesn't happen with fiat.

Which one would you choose?

infact "we" can just seitch to any other infinite coins cause again, theres barely anything but grandfsther clauses tying bitcoin to any realworld value
