Could conflict among “competing governments” be taken care of by treaties? Treaties?–enforced by whom? I once asked Ayn Rand about the feasibility of such treaties between sovereign “competing governments.” She looked at me grimly and said, “You mean like at the U.N.?”
Economic competition presupposes a free market. A free market cannot exist until after force has been barred. That means objective law, backed up by a government. To say it can be backed up by “competing” force-wielders is circular. There is no competition until there is a free market, and some agency has to protect its condition as a free market by the use of retaliatory force.
