> Now you could probably take that judgement to a majority of staking validators and force their compliance.
That's if the validators reside within the courts jurisdiction. And another challenges is to find out who these validators are. While the wallet addresses are public, there is not a registry one can use to look up names and home addresses.
2/3 of the ethereum staking validators are domiciled in the United States, because they are hosted on centralized ethereum wallet services in that jurisdiction which offer staking. Or at least it was at one point after merge activation; I haven't checked in a while. It is quite easy to see where the stakers are located through traditional blockchain analysis tools.
For more decentralized blockchain the court has no way to force shutdown of a smart contract.
That’s the whole value proposition.
