Just like that judge that ordered the DAO hack to be reversed?

No, a judge will never order anybody to enter into a different smart contract just like they don't order people into regular contracts today.

Judges have a lot of power, but they can't enforce their views on people not in their jurisdiction without the cooperation of judges and governments in other countries. This is one of the major drivers behind the development of smart contracts. I think that for those situations where 'dumb' contracts suffice they will continue to be used and the courts will continue to have their power. But precisely for those situations where the courts do not have such power smart contracts are a potential solution.
