Even if money (BTC, etc.) is stolen at gunpoint? Blacklisting stolen money is a marvelous idea.
Oh GTFO you UnSavoryGarnish.
"I know it looks like I sent money into that exchange, but I was actually held at gun point so please reverse it!"
Let's start using social security numbers as our addresses while we're at it. So stupid.
If a thief is caught and still has the money then should they be forced to give it back? If the thief gave it to their brother who still has it then should the brother be forced to give it back? If the thief "bought" lunch from their brother-in-law who happens to own a restaurant then should the brother-in-law be forced to give it back? When is the stolen money no longer rightfully the original owner's?
is this also true in your jurisdication:
(both cases assume you can proof that you did not know about the theft)
- you buy a stolen car, police finds you and take it back to the rightful owner
- you sell something to a robber but you dont have to give the money back
thats the different of money vs goods and thats why it is important that money is fungible.
most coins you own (i mean fiat) were already used to buy drugs and have certainly been stolen at some point in the past. do you think a merchant should refuse to take them from you? is this true in your country?
(also: please explain to me HOW do you want to implement blacklists - i dont see a way which would work without multiple forks running in parallel)
