Division of Labor
The first link explains why the collective consciousness of humanity is not ready to abandon the concept of property, and that rather than ignoring the matter we should rather update the theory of property and move forward.
Private property initially aimed and actually served to reward the laborer with his product. Unfortunately as industrial capitalism developed the theory of non-Proviso Lockeanism (the historically theoretical background for most legalistic forms of private property) essentially failed to account for the particularly destructive material relations and exploitative social forms of industrialism and is how the revolutionary aims of private property were eventually dialectically inverted to instead divorce the laborer from his product. Since the development of industrial capitalism neither the complete theory of Proudhon or Locke (Proviso Lockeanism) have been practiced, and I believe it's safe to say that both theories would have positive social and ecological implications especially within the context of global corporate capitalism.
The second link beautifully ties together the intersection of both Proudhon, Stirner, and Locke's theories of property. Locke's Proviso's are likely the emergent norms of Proudhon's theory, the norms that Stirner considered somewhat unnecessary for a "Union of Egoists" and Proudhon left to persons practicing of reciprocity or the Golden Rule.
