Markets and commerce are not created top-down, they are emergent behavior:
...“no one” made markets. No one put out rules for when a market should or should not exist, much like the footprints in the snow following a fresh storm, these markets emerge from the self-interested actions of millions of buyers and sellers each responding to hundreds upon hundreds of incentives every day. Indeed, no one ever sat down and said, “you know, we have this major problem here – there are simply not enough things out there for all of the people who want them, so, let’s have this thing called capitalism and see how it works.” It simply didn’t go down that way, and discussing “markets” in the anthropomorphic way that is often done, particularly in these lines of inquiry, really takes us away from appreciating that market activity is an emergent process. Yes, it does operate in a richer institutional and intellectual framework and yes the “rules” of the game do alter when ends up being for sale or not, but simply condemning “markets” as allowing “everything” to be sold quite misses the point.
