Hopefully we would all learn that the community can pull together for the sake of justice?
In any case, I imagine this would depend almost entirely on what the miners are willing to do, and if a majority of the hashing power would support it.
How sure are you that 100% of all miners and all mining pools in the entire world will honor the agreement not to put such transactions into the chain in the first place?
If even one miner somewhere in the world puts such a transaction into the blockchain, how would you suggest the remaining miners handle the situation? Do they ignore that block, or do they accept it and build on top of it?
