In a system run by people, the transaction could be reversed, traced, and the culprits eventually brought to justice. In a system run by algorithms, designed to avoid oversight by people (governments), there is no such powers. There's no reversal. There's no checking the name on the account the transfer was to. It's just gone. I do not understand why people who have legal intentions would want to be part of the crypt…
Another benefit of some blockchains: incredibly low transaction fees.
Another benefit: smart contracts.
I don't understand why you need to straight up lie.
