In continuity with the classical liberal tradition, geolibertarians contend that land is an independent factor of production, that it is the common inheritance of all humanity and that the justice of private property is derived from an individual's right to the fruits of his or her labor. Since land by economic definition is not the product of human labor, its ownership cannot be justified by appealing to natural human rights. Geolibertarians recognize the individual civil right to secure exclusive possession of land (land tenure) only on the condition that if the land has accrued economic rent, its full rental value be paid to the community deprived of equal access. This non-distortionary system of taxation, it is argued, has the effects of returning the value that belongs to all members of society and encouraging landholders to use only as much land as they need, leaving unneeded land for others to occupy, use and develop.
