Sorry you can't get away with that sophistry. You say that the protection is needed but that you should not have to pay because you don't "want" it. If its needed, "want" doesn't arise.
See my example of "needs" earlier in this thread. If you like, I can substitute 'need' with 'want' if you like. No prob.
See my rebuttal. You confused things that you can do yourself with things that you need society to do for you. You need society to provide 24/7 care for the violently mentally ill. Since you are using the service society provides, you must pay for it through taxation.
