If you just replace "financial incentives" with "status incentives", he's fairly correct. I view a lot of community contribution as a pursuit for status and recognition, even if it's done behind an anonymous avatar that proxies for the person's ego, with the ultimate unconscious objective of attracting a mate who recognizes your high standing in the community as judged by your peers. Financial incentives are just a subset of that psychological process that economists focus on because it's liquid and quantifiable. The beautiful thing about capitalism is that it takes that selfish part of our psyche and tries to point it in a direction that's productive, instead of pretending that such selfish motivations don't exist. Self-serving psychopaths have a hope of contributing positively to society by simply self-maximizing. In any other system that makes no allowance for healthy self-maximizing, they are only capable of destruction. Obviously the outcome is a disaster when the profit motive doesn't align properly with what's good, so that's where regulations come into play.
