And nothing you can say will change my view of it.
Ah, the characteristic sign of the truly irrational. I actually agree with a good part of what you said in that post, but with that last line you lose all credibility to having a reason-based argument. If no reason could change your mind, then your mind is, by definition, unreasonable (not based in reason).
I'm also curious how you expect to fund the essential portions of the government. The "required for living" stuff like a military strong enough to prevent invasion (not to be confused with what the US actually has), and the critical portions of the government apparatus (like employing the people who decide what those voluntary taxes should be, and the infrastructure to collect and count the votes or otherwise implement the method of selecting said government), and so on; that also costs money, you know?
Do you charge it only to the people who use "products or services that are NOT required for living" and let them - the ones with disposable income - pay more than the fair value of those products and services in order to support the freeloaders who benefit without cost? Or do you institute a tax on things like property (in the sense of shelter and a place you can secure as your own) and, when somebody points out that many such things are actually *more* "required for living" than a monetary income, put your fingers in your ears and go "LALALALALALALA" over and over again until they go away?
Oh, and if you *do* plan to collect the entire tax base off optional services, how do you prevent somebody from setting up a non-government business that provides the same product or service but costs less (because it doesn't have to bear the overhead of also running a country)? Do you make competing with the voluntary-tax services illegal (no for-profit prisons, say)? Do you allow competition on the basis that the government is inherently more efficient and will win in the free market? Do you allow competition but cripple the private businesses by not allowing them privileges that the government has (say, the right to forcibly detain or injure people) and thus force those who want effective services to pay their taxes to the government anyhow?
I'm sincerely curious whether you've thought of any of this before, or have answers now. Your post suggested that yes, you have an answer for all the questions... but it also seems self-contradictory and I wonder how you plan to resolve such issues.
