You can't have indefinite supply inflation without a centralized parties, that's what you seems to be missing here. The problem is once you start deciding to give Bitcoin core or someone else the right to arbitrarily print SATs the government or other parties will get involve by either buy them out or corrupt them even more so they can benefit first, thus we come back to square one. The problem is once you start to say we will print this much for this reason then you will always find reasons. The difference with Gold is It's difficulty to be mined, you can't just say print this much amount of gold to pay miners more. If you do that with Bitcoin you just have another worthless fiat currency.
