Ironically, providing a means to reverse disasters is probably good for Etherum; it reduces the number of investors who leave because they've been burned.
Today, I (generally) get one set of a laws if I live in a particular geographic location, but a "centralized" ETH committee/board could serve as an authority for some set of actions by individuals unbound by geography.
Some people just want that choice.
I believe it should be quite possible to formulate such a thing as part of a smart contract in which the ETH committee/board may always interfer if they desire if this is what people want.
If code or asking Vitalik nicely enough is law, I think I'll stick with lawyers, thanks...
