you are just reiterating long debunked concerns that are listed on this little chart from 10 years ago

The right, blue section, on the right side under the "Government" category are the ways that they will respond
Banned is already over and done with, the chinese, russians, and USA all have given up trying to do that
they have started trying taxed and regulated but that's not going to work either, because there is so many countermeasures you can use to avoid them, and some are also just the sane thing to do because of the adversarial situation with shitcoin casinos trying to accumulate sats running as the House on people who are trying to catch the Next Big Thing ™️
it's not exceedingly easy to avoid getting logged as having sats but the more you have, the easier it is to access ways that you can avoid leaving records in accounts of honeypots, i mean shitcoin casinos and neobanks and whatnot, so that's Taxed
and Regulated, that's this OFAC, miner blacklisting of UTXOs
if you understand the full game theory of why Bitcoin has UTXOs you will understand that they can't hold a net around UTXOs without control of ALL jurisdictions, just one miner puts your UTXO spend and oh, now they have 2+ to chase after, or better still you coinjoined it with 10 other people and now there's 30 UTXOs they can't control, it's a hydra
