Larsson's paragraph is a faithful and economically sound description of both the tragedy of the commons and the enclosure movement. His example — that a resource open to everyone is at risk of overhunting or overgrazing — is precisely Garrett Hardin's "tragedy of the commons" (1968): where a resource is held in common and access is unrestricted, each user rationally takes as much as possible because the benefit accrues to the individual while the cost of depletion is spread across all, so the resource is degraded to everyone's ruin. Larsson's remedy — restricting access and vesting exclusive rights so that the owner captures the fruits of investment (digging wells, improving grazing) — is exactly the economist's answer: exclusive property rights internalise the externality, aligning the private incentive to conserve and invest with the social interest. That is also the logic of the historical enclosure movement in England, in which open common fields were fenced ("enclosed") and converted to private holdings, which raised productivity and investment (albeit at a real social cost to commoners dispossessed of customary use) — the very "development of land" Larsson praises. So on the descriptive point I agree with him.

Do property rights only develop or flourish if delimitation takes place? Here I partly disagree. Delimitation — the spatial defining of the area over which the right runs — is closely linked to property rights, as Larsson says, and some notion of extent is logically necessary (an exclusive right must be exclusive over something). But it does not follow that precise delimitation is a precondition. Property rights can and do exist and flourish under vague or approximate boundaries: customary and Indigenous tenures, general-boundary registration systems (where the exact line is deliberately left undetermined), and possessory rights all secure meaningful exclusivity without a surveyed delimitation. Rights and delimitation co-evolve; delimitation sharpens as it becomes worthwhile, but the right can precede and exist without a precise boundary. So "only if delimitation takes place" is too strong — it conflates the existence of a right with the accuracy of its spatial definition.

Is the converse true — does the development of property rights inevitably lead to more delimitation? Generally yes, but not inevitably. Harold Demsetz's theory of property rights (1967) supplies the mechanism: rights become more clearly defined and delimited when the benefits of internalising externalities exceed the costs of doing so. As land grows scarcer or more valuable (population pressure, a new market, a resource discovery), the gains from securing and precisely bounding it rise, and pressure for finer delimitation, survey, and registration follows — which is why cadastral systems intensify as economies develop. But the driver is a cost–benefit calculus, not inevitability: where land is abundant and of low value, the cost of surveying and maintaining precise boundaries can exceed the benefit, and general boundaries or informal tenure persist indefinitely. In short, stronger and more valuable property rights tend to pull delimitation along with them, but only to the extent that the value at stake justifies the cost of delimiting.
