Delimitation and the Origin of Property
Every theory of property must answer how an unowned thing becomes owned. The dominant libertarian answer is use: Locke’s labour-mixing and Rothbard’s first-use-first-own. Os Fundamentos Objetivos da Justiça gives a different one. Ownership is a legal relation, and a relation needs two determinate terms — so before a resource can be owned it must first be a thing, a unit distinguishable from everything else. What accomplishes that is the objective definition of its boundary. On this account use is evidence of possession, never a source of title.
The argument
The book’s starting move is to separate three things that the labour-mixing tradition tends to run together: the object, its boundary, and the legal relation that attaches to it. Property is none of the first two. It is the relation between a subject and a previously individuated unit — which means individuation is prior to ownership, not produced by it. First the unit is identified; only then can the relation hold. Never the reverse.
That ordering is what generates the argument against use. A person can use a rented car, work with a borrowed tool, or live in a lent house, and in none of those cases does the using alter who owns the thing. So use cannot be what creates title; at most it demonstrates possession — that someone is with the thing, not that it is theirs. O uso pode demonstrar posse — use can demonstrate possession — but not ownership.
Labour fares no better, and the book’s objection to it is narrow: transforming a resource changes its content, and that does not explain why the resource constitutes a juridically distinct unit in the first place. Work alters what a thing is like; it does not account for where the thing begins and ends.
What remains is the boundary:
A propriedade nasce quando uma unidade da realidade passa a possuir limites objetivos suficientes para distingui-la das demais e permitir que sobre ela recaia uma relação jurídica.
— Luiz Liberatus and Pedro Távora, Os Fundamentos Objetivos da Justiça
Property arises, that is, when a unit of reality comes to have objective limits sufficient to distinguish it from the rest and to let a legal relation attach to it.
Perimeter, not interior
The consequence the authors draw immediately is that appropriation works on the edge of a thing rather than throughout it. Delimitation operates on the perimeter; individuation then reaches everything enclosed within it. One need not know, or use, or transform what lies inside.
This is where the theory does visible work. A farm is not property because someone cultivated its whole extent; it becomes an individuated unit because its limits were objectively defined. A territory does not depend on the continuous occupation of all of its points. And once established, title does not lapse for disuse: an abandoned lot is still an individuated lot, an empty house still a distinct unit, a car parked for years still the same thing. Ownership persists because the individuation persists, ending only by legitimate transfer, abandonment, or some other legal ground.
The same principle runs backwards to the self. Self-ownership is, in this system, the first application of delimitation rather than a separate axiom: the reflexive consciousness that distinguishes the self from what is not the self performs exactly the boundary-drawing that external property later requires. Property theory and the theory of the person share one mechanism.
Where it collides with the tradition
This is a genuine break with homesteading, not a restatement of it, and the disagreement is sharpest precisely where Rothbard’s rule is most consequential.
Rothbard’s negative corollary is that ownership requires use, so a claim to land never put into production is void — which is the premise that lets him call whole classes of historical land title illegitimate. Delimitation removes that premise. The book is explicit that once established, title does not depend on continued use, and that a farm is individuated by its defined limits rather than by cultivation of its whole extent; what it never says is who acquires title when a boundary is first drawn. So it does not directly pronounce on the titles Rothbard voids. But it has removed the only test by which he voided them, and put nothing in its place — which is the next objection.
The gap also runs the other way. The labour-mixing tradition has an answer, however contested, to why appropriation wrongs nobody: the appropriator adds something of his own, and the Lockean proviso limits the taking. Delimitation as stated in this book supplies no comparable constraint. Nothing in the account explains why one person’s act of drawing a boundary binds everyone else who never consented to it — the question the proviso exists to answer — and no equivalent of the proviso appears. A critic would say the theory identifies the conditions under which a thing can be owned while leaving the entitlement unargued: boundaries make ownership possible without making any particular claimant’s ownership just.
The book does not answer this. Its one structural argument of the right shape — that aggression is incoherent because a juridical sphere cannot have two originary authorities at once — is made about self-ownership, whose exclusivity follows from the individuation of the subject himself. Nothing extends it to a newly delimited external resource, where the question is precisely which of two claimants the boundary belongs to. The gap between the two cases is where the theory most needs work.
