Blockchain is not a place where anyone has the final say, including the government. If someone commits a crime, they should be arrested, not the money. Money is never dirty; it is the people who are dirty. Shouldn't it be the criminals who face the law? Funds whose source is unclear should belong to the community and should return to society (the decentralization of the blockchain) rather than to any individual or government. This is the meaning of decentralization, as the current government is still in the stage of being "legal robbers".
