To arrest, fine, or otherwise forcefully prohibit peaceful conduct is to aggress against a peaceful person; a serious violation of the 3L Principle.
When people enforce victimless crimes, they become aggressors.
Regardless of the motivation, title, uniform, badge, or status, the first person who aggresses is always wrong. We should legally sanction such a person.
Outlawing victimless crimes is doubly wrong. It punishes peaceful people for acting according to their will, then forces everyone else to pay the costs of enforcement and punishment.
Prohibiting these voluntary behaviors is expensive, rarely effective, and defines peaceful people as criminals. It just creates an underworld where genuine acts of aggressing are more likely.
The more laws and restrictions there are,
The poorer people become.
The more rules and regulations,
The more thieves and robbers.
