Sorry, but you're wrong. Listen to/read this: http://www.econtalk.org/archives/2015/09/tina_rosenberg.html http://www.econtalk.org/archives/2015/09/tina_rosenberg.html Summary: most of the world doesn't allow selling internal organs, but Iran does, and it's been interesting to study how that's developed. Explicit exchange of goods for kidneys isn't allowed in the US, but you can join a "donor chain" which, when you donate to another person, through a chain of people, someone you care about can eventually get a kidney. The chain acts as a central clearinghouse in the absence of direct monetary exchange.
