What would happen if a court orders to take down a smart contract

Pre-merge, nothing. Now you could probably take that judgement to a majority of staking validators and force their compliance.

For more decentralized blockchain the court has no way to force shutdown of a smart contract.

That’s the whole value proposition.

Every non-criminal contract is essentially just question of money (or some property).

So take down contract, equal to return money (property), nothing more.

Question could happen in cases like Ponzi scheme, where subject just have not enough money (property), to cover liability, but this is ordinary thing, usually covered by Insurance Company or by government.

Courts can only make orders on parties of lawsuits. It can’t make broad orders against groups of people or non-entities.

Orders who?
