You seem to be making some assumptions about the domain name system. One assumption you are making is that human intervention is needed to decide. Do humans decide #hashtags for Twitter ? Another assumption you seem to make is that domains should be monetized. That may be the biggest mistake ever made in Internet history. The same can be said for IP Address Space. When you have the true cost of a $6 domain name being delivered for 50 cents, that is a mark-up that attracts many business people. ICANN of course keeps those evil people out while it enjoys the revenue stream to do as it pleases. End domain monetization and you end ICANN.
