If I'm not mistaken, controlling most miners would give them de facto control over which transactions would go through, right? They could modify the ones they control to check with Palantir whether or not a transaction is allowed. Then regular people would have to hope to catch a "free" node outside the US (and probably outside Europe or NATO as well).
Printing on the other hand, i.e. inflating the supply of bitcoin to more than 21*10⁶ would mean a hard fork and probably a substantial rewrite. But if almost all the nodes are centrally controlled, there probably wouldn't be much opposition and said fork would be adopted, leaving the non-western "free nodes" with the old code.
Might as well just launch a CDBC and plain outlaw bitcoin altogether.
Well, there's more than one way to slice it but either way, the people with the most guns win I suppose. Lovely.
