Benkler gets to the bottom line here:
There is an abiding skepticism, born of many years in the industrial age, about the sustainability and plausibility of nonmarket-based cooperation and productive collaboration. We have now, on the other hand, almost two decades of literature in experimental economics, game theory, anthropology, political science field studies, that shows that cooperation in fact does happen much more often than the standard economics textbooks predict, and that under certain structural conditions non-price-based production is extraordinarily robust.
There is some good give and take in the comments section of the post.
This one will be interesting to watch.
