So no one has put a gun to your head, you're simply afraid that someone will. Now we're finally getting somewhere, let's take this a step at a time.
You mean that if you're convicted for tax evasion, you can still stay at home and enjoy life, and nobody's going to use violence on you, like trying to put handcuffs, or put you in jail or something ? And if you try to defend yourself against people with uniforms coming to use violence on you with a weapon, you're not going to get any guns against you ? Nothing physical will happen to you if you refuse to pay your taxes ? You will simply be denied access to state services you're not paying and that's it ? Nothing physical will happen to you and you will happily go your way ?
You are right in the sense that you will be subject to violence if you don't obey but you can organize your life to be less subject to this violence.
