Demsetz bases his theory of private property formation on the anthropology of Canadian indigenes near Quebec during the fur trade. He claims that soaring prices for furs stimulated the local indigenous peoples to form territories so they could more effectively husband their fur resources (mostly beaver populations). My question is twofold: (1) Did contact with the French devastate the indigenous populations as was the case further south, in both North and South American; and (2) did the privatization of the resource (in landed property) lead to local animal extinctions due to intense market pressure for furs?
