Money is a curious sort of behavioral information network, in that the information is destroyed at every hop. If you pay five dollars at my hot dog stand, I accept the exchange in value without the slightest clue if the money came from tutoring orphans, or human trafficking. I'm honestly unsure which has greater perverse incentives and moral hazard: behavioral opacity, or behavioral transparency. (Note that the only entities that have access to at least some of the information of each money hop are governments, banks, credit agencies, and to some extent online silos like Amazon.)
