Commodification

Abstract Are there some things that should not be commodified? By “commodification” we mean the process of transforming a good or activity into a commodity available on the market. How extensive should that market be? For instance, should transplant kidneys, water, professional soldiers, or sexual services be available on the market? Are there reasons to prevent the buying and selling of certain kinds of goods or might we permissibly allow the commodification of everything that can be commodified?
