This seems pretty simple to me.
Decentralized crypto-currencies are all about consensus.
Vitalik suggested a hard fork rollback.
The majority seem to want it...that's consensus!
Now roll it back.
Note - I was not affected by this DAO/ETH situation.
Thats more or less true with a soft fork, but a hard fork, is like going back in time an change the law.
Example:
You go into the casino and win legally 50 Million with a new technique. The casino owner is bankruped and the stock is dropping by 50%. He and his stock owners decide to go back in time and change the casino rules, so that the one, that wins the 50 Million at this day doesn't have to be payed out. Fair?
But even the soft fork can be somehow discussable:
The winner won the 50 Million, that can only be payed out a month later. But the Casino owner closes the casino, and sets all escrow funds on hold.
