Well, land is certainly essential, so you want to rule out taxing land...? Somehow, I kinda figured it'd be something like that. Nonsense. A voluntary tax is one that is paid in return for benefits received, like a tax on land value. - - - Updated - - - Such claims are absurd. You are making a fool of yourself.
Government in the sense of a sovereign authority over a given area of land is necessary to an economy above the nomadic herding level. You are factually incorrect. Government cannot take any form but sovereign authority over a specific area of land, because that is what government IS. That claim is false. There are many services that are natural monopolies, and consumers can get better service from a public monopoly than competing private firms in such cases. Security is one such service, as proved by the invariable victory of public monopoly in competition with private providers. Wrong. Many market failure conditions imply that a monopoly is preferable. Issuance of currency is one. False premises do not support a conclusion, sorry.
