Yeah I think you’re kinda right. I was more thinking about haspower capture, but node capture might also work. One option might be for the US to hard fork with their hashpower, and legislate that commercial miners, US pools and custodians/ exchanges only point hash/ transactions to their fork. These centralised entities would likely have to comply, but foreign ones probably wouldn’t. So there is a ‘US approved’ fork and a non-us approved fork. So then which would be the ‘real’ bitcoin, well that might depend on where the hashpower went. If the US was able to command that, I think it could arguably maintain a narrative that the US bitcoin is the ‘true’ bitcoin.
