There are many actions the state's agents take that would be considered criminal (in the harm sense, rather than LawIsAnExcuseToDoHarm) if done without the fancy uniforms, pomp, and Orwellian terms. Voluntaryism does not put the state on a pedestal; people are judged by their actions.
- If you kill someone (outside of self-defense), it's wrong, even if you call it "war".
Kidnapping someone is wrong even if you think they've broken a "law" and you're wearing a uniform with shiny buttons.
And so on and so forth.
