Property rights do not exist as natural rights but as social conventions

The argument

This argument supports the view that taxation, even if called theft, can be justified, by denying the libertarian premise on which the 'theft' charge depends: that property rights are natural rights existing prior to society. They are not, the argument holds, but social conventions — and conventions can legitimately include taxation among their terms. The 'taxation is theft' claim assumes a person has a natural, pre-political right to the full fruits of their holdings, which the state then violates by taking a share. But what a person owns is not a fact of nature; it is the product of a dense system of human conventions — laws defining what can be owned and how, courts enforcing claims, currencies, contracts, registries of title, and the collective agreement to honour them all. 'Your' income arises within a market, a legal order and an infrastructure that society maintains; outside that web of convention there is possession by force, but no property in any meaningful sense. Property is something societies construct, not something individuals bring to society fully formed. If property is conventional, then its terms are set by the society that constitutes it — and those terms have, in every functioning society throughout history, included taxation. Taxation is not an external raid on a pre-existing natural entitlement; it is one of the built-in conditions of the very institution that creates and secures property in the first place. One cannot accept the system that defines and protects one's holdings while rejecting the terms on which that system operates. There is no pre-social property right for taxation to violate. From this standpoint, the 'theft' framing rests on a fiction. Because property rights do not exist as natural rights but as social conventions, this argument holds, taxation can be justified.

Premises

Counter-arguments

Establishing that property is conventional does not establish that any particular convention is just. Slavery, coverture and hereditary serfdom were all legal property conventions constituting what could be owned and by whom; that a society's rules created them settled nothing about whether they were defensible. The argument moves from an account of what property is to a conclusion about what may be done with it, and the gap between the two is exactly where the justification would have to go. The historical premise compounds this. That every functioning society has taxed is a fact about societies, not a licence — every society has also had coercive practices later judged wrong, and universality is not validity. Reading taxation as a 'built-in condition' of property makes it true by definition that nothing a state does to holdings can violate them, which disposes of the objection by stipulation rather than by argument. The target is also displaced. Natural-rights theorists generally accept that legal title is conventional and locate the moral claim elsewhere — in self-ownership and in what a person's labour produces. On that view, conventions can track or fail to track a prior entitlement, and pointing out that title depends on courts and registries does not reach the claim being made. The tacit-consent move that follows — one cannot accept the system while rejecting its terms — is the familiar argument Hume answered by noting that consent inferred from residence is not consent where leaving is not a real option. And the reasoning does not support the position it is filed under. Concluding that there is 'no pre-social property right for taxation to violate' is the claim that taxation is not theft, which is a different position in this question, rather than the claim that it is theft and is nevertheless justified.

Rejecting the premises

[Rejecting P1] Natural-rights theorists generally accept that legal title is conventional and locate the moral claim elsewhere — in self-ownership and in the product of one's labour — so demonstrating that title depends on courts, currency and registries does not reach the premise their argument actually uses. [Rejecting P2] The conventionalist account may be correct without licensing anything, since slavery, coverture and hereditary serfdom were also property conventions constituting what could be owned and by whom, and their conventional status settled nothing about their defensibility. [Rejecting P3] That every society has taxed is a historical regularity rather than a justification, and treating taxation as a built-in condition of property makes it true by stipulation that nothing done to holdings can violate them; the accompanying appeal to accepting the system's terms is the tacit-consent argument, which fails where leaving is not a real option. The conclusion is also that no pre-social right exists for taxation to violate, which is the separate position that taxation is not theft.
