Are judges going to manage to identify and compel enough miners (or devs, i guess, assuming the miners adopt the compelled transaction revert version) to have enough hash power to win a fork?
this could easily be combined with legislation providing tools to make it harder and harder to participate in mining off-fork.
US financial laws have been very useful for the gov't to be able to de facto give it worldwide jurisdiction in some areas, I think there would be relatively few qualms about continuing down this path. Especially if (for example) Robinhood and Coinbase were forced to follow along. At one point the "blessed" thing will become the only place you can really operate.
For example, the court could declare that this transaction was illegal, and anything spent from it is also illegal forever. The ledger is open, so courts can compel exchanges to watch for such transactions and report anyone that can spend coins derived from them (exchanges have already been forced to comply with KYC).
This would destroy the real-world value of this block, basically making it a digital equivalent of dirty money.
