At that point I guess BTC becomes the unit of account for the world as the dollar will have hyper inflated into oblivion and printing to buy bitcoin is a sort of end state that would signal the end of the dollar system?

I personally can’t wait until everything becomes natively priced in sats and we can just leave this fiat era behind us, though I have this sinking feeling that the powers-that-be will try one last trick before finally giving into Bitcoin, and that would be the CBDC (though probably called something else).
