It's funny to see that this was my most downvoted comment ever on HN.

Looks like blasphemy against the “free market” religion isn't tolerated here.

You first have to agree on a definition of free in this context. When Adam Smith was writing the Wealth of Nations most of the transactions in the market were between entities with more or less comparable power. Local people bought stuff from local suppliers. This is very much not the case any more when it comes to transactions involving private individuals on one side and corporations on the other.

What commodity isn't ruled by intergovernmental agreements, a cartel, a monopsony or something else?

Please name just one.
