“Property rights develop to internalize externalities when the gains of internalization become larger than the cost of internalization. Increased internalization, in the main, results from changes in economic values, changes which stem from the development of new technology and the opening of new markets, changes to which old property rights are poorly attuned [G]iven a community's tastes… [for private versus state ownership], the emergence of new private or state-owned property rights will be in response to changes in technology and relative prices.”
Harold Demsetz, (1967). "Toward a Theory of Property Rights." American Economic Review 57 (May, No. 2): 347-359. p. 350, as cited in Eggertsson (1990; 250)

Context: Its first ethical precept is the identity of means used and aims sought. The ultimate end of all revolutionary social change is to establish the sanctity of human life, the dignity of man, the right of every human being to liberty and wellbeing. Unless this be the essential aim of revolution, violent social changes would have no justification. For external social alterations can be, and have been, accomplished by the normal processes of evolution. Revolution, on the contrary, signifies not mere external change, but internal, basic, fundamental change. That internal change of concepts and ideas, permeating ever-larger social strata, finally culminates in the violent upheaval known as revolution.
