If the bitcoincommunity will try to creating an authority what block 'blacklisted' public addresses to send and receive transfers, if impossible to confirm the transfer, the value is vault =0. Haha, and no more hack, and no any country authoity to take anything.
Early implementation of this make bitcoin safer.
The only question is: who will create this one? if the community, then its cool, if a state organised something, then we are hecked...
Blocking the last 5000 'bitcoin-out' from mtgox, and if someone reclame the coins, just need to proove the origin(mining-buy).
If any transfer connected to familiar to employees to gox, then stay blocked, unlock=handling the private key to this coinauthority and they redistribute to the rightful owners.
(so the confiscated coins will be 0 values hihi)
With real money you can not make the same.
