The DAO fork never would have hit production if users had not been chosen to run it. The software update even had a switch people had to set, choosing whether to run the fork or not.

The Parity project later requested a rescue attempt for themselves and their wallet users, and the community strongly resisted the idea. Parity was run by a cofounder of Ethereum, and the issue was way more clear than someone claiming without proof that they'd lost their keys; if Parity couldn't get a rescue done, it's not likely to happen again for anyone else.

Certainly it'd be difficult to get an international community to bend to the demands of a court in one jurisdiction. Even if they forced the issue in that one jurisdiction, it'd just be a fork, probably with little value.
