The Limits of Markets: Kin.

Markets either facilitate our families, tribes, and nations, or they prey upon our families tribes and nations.

Markets and the consumption they provide us, do not create limitless goods. At some point we are no longer advancing our kin, but instead, preventing a future for them.

There is no incentive for good families to cooperate and refrain from parasitism if they sacrifice their lineage for others.

Either cooperation is mutually beneficial and mutually non-sacrificial, or it is just theft by other means.
