That's not at all true, and I will state this as an unfortunate side effect of the intrusion or "the state" into everything. Morals aren't governed by state law. Doxxing someone is wrong in nearly all cases. That's not something codified into most laws, but it still doesn't make it right. State laws often carry burdens that most aren't aware of. Libel is a civil matter. There are fairly well established precedents for handling this sort of thing. It is harder to pursue given the nature of the locations (or lack of knowledge of those locations) of certain parties.
