I think he's essentially correct on the macro trends that will move the world more to this kind of model. On the specific point on what's holding back a more distributed/networked model of production, I think one obstacle is that labor is not easily "commoditized" in a way that facilitates trade (see http://crowdresearch.org/chi2011-workshop/papers/horton.pdf http://crowdresearch.org/chi2011-workshop/papers/horton.pdf for more on this).
