What he's speaking of to me is a basic law of nature that's seen in any system where independent self-interested entities compete for limited resource(s), i.e an ecosystem. When the forest canopy grows too large and blocks out energy from hitting the forest floor, the floor, unable to obtain adequate resource, dies. This decreases biodiversity of the system leaving the forest more susceptible to disease and effectively decreases adaptability of the system as a whole to external threat. The dead floor becomes kindling for a fire and the forest burns which is in essence a homeostatic redistributive mechanism for the limited selective resource; energy. New undergrowth grows, biodiversity restored until the process repeats. Human economies are similar by the above definition of ecosystems. In this case money replaces energy, which is a surrogate for selective factors that drive human evolution. When wealth consolidates at the top, the floor becomes kindling for a fire. Historically this has been met with a burn of the incumbent system; revolution; redistribution. A new system is formed until the cycle repeats. The point is the viability of any ecosystem is dependent on equitable flow of resource within the system. This view of economies has me worried about cryptoeconomics. To me it appears that mining/validating will lead to consolidation of wealth, rent seeking, and a new class of crypto elites that will eventually need to be burned.
