But that's not what this is. This isn't a victimless crime. It's a victimless tort, which is even more nonsensical. A tort, by necessity, requires a party that has had some demonstrable wrong committed against it. That Trump was accused of committing a tort is evidenced by the fact that he was given a civil trial instead of a criminal one.
I'm not a lawyer, but I'd argue that Trump was deprived due process here. He was slapped with what amounts to a criminal fine via a civil process (along with the lowered burden of proof that entails). A law that allows criminal penalties to be applied under the guise of civil jurisprudence (but without a "wronged" party) is on its face unconstitutional.
