I think that if your contribution is entirely up to you there is a powerful incentive to want to negotiate over it, to get something for the money, to control it or at least not let it sanction evil or incompetence. Any feature or incident concerning the government which is a cause for unhappiness can become an excuse to withhold funds by somebody.
So far so good.
This is basically the Federalist critique of the government of the Articles of Confederation, which also had no taxing power.
Of course. The issue of actual slavery was the moral issue of substance that would come next. A society free of any type of economic “slavery” was not possible at the time to realistically address.
And it still isn’t now. But we’re speaking in the realm of political philosophy and whether or not taxation is moral. I haven’t seen an argument for forced taxation being moral yet. The closest justification I’ve seen is essentially, [paraphrasing] 'Well, I can’t think of a way to make it work with out it, so things would be bad."
The essential hurdle in making voluntary financing of a free society is first that philosophical change mentioned above. The political and structural hurdles to make it a reality are premature to establish because they will necessarily rely on what is realistic at the time it is to be instituted.
So speaking of specific methods becomes very problematic. There are too many assumptions that cannot be realistically estimated correctly. When enough people in a given society hold to the principle that the nature of government is its monopoly on retaliatory force and, as a corollary to that, understand that the fundamental function of protecting the rights of the individual are limited to the force related functions of: Defense, Objective Law and Law Enforcement,-- Then, the landscape of that society will be open an array of creative financing options which will seem “impossible” to us now.
The way I imagine the actual structure is where people pay directly for all private and government services they receive (and would never expect not to). When they don’t, they don’t receive those services. There will be indirect benefits to those of lower economic positions (for instance, the amount they pay towards police protection while still being protected), this is the logical consequence of a free society. (Not every customer at Starbucks has contributed equally to the free wi-fi, have they?) In fact, the indirect benefits for all the members in that society woulld be impossible to quantify.
*I should note that a first step towards REAL private property ownership is very likely a moral issue that comes before complete voluntary financing. This is definitely an area where objective law is more easily able to be seen as… objective.
“Any program of voluntary government financing is the last, not the first, step on the road to a free society—the last, not the first, reform to advocate. It would work only when the basic principles and institutions of a free society have been established. It would not work today.”
