It sounds like you believe the only legitimate state is one where a criminal suspect can say "no thanks" and walk away in response to a court summons or arrest warrant. What brings anyone to walk into a courtroom to face charges at all, other than the knowledge that they will be tied to a chair and wheeled in if they refuse?

Of course the state uses violence to extract compliance with social norms. That's what it's for. The much more interesting questions are about which norms it should enforce (criminal codes) using how much force (sentencing, prison conditions, police rules of engagement, etc) and subject to what controls (due process, civil rights, etc).
