Let's say it is discovered that this wallet contains stolen bitcoins from several forum users. How could they retrieve the coins? Is it ethical to put a freeze on the coins at exchanges, if this were possible?
Perhaps the best course of action would be to try to steal the wallet back, vigilante style, then return the coins to their rightful owners according to the block chain. Less some bounty of course.
If you don't want regulation in a currency don't expect to be able to do anything about it when something you don't like happens. It's bad it does but whining about it when it's a central, built in part of the currency is just fucking pathetic.
