Extinction

Explanation:

Extinction is the disappearance of all members of a species. A species is considered extinct from the moment the last individual dies. In the case of species that reproduce sexually, extinction is generally unavoidable when only one individual of the species remains, or only individuals of the same sex, since there is no way they can reproduce to give continuity to their species.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
