I write alot about endgames because it's important to visualize the goal. I see free market at best as a transitional, or dynamic, goal towards equilibrium. There will be no peace under a currency system because no law can restrain immorality when the means for survival can be bought. The endgame of either a few owning the world's resources or everyone owning the resources are two opposing endgames. Both endgames can only exist in transition towards the other state. Once the endgame is finished the system becomes more static and an equilibrium, however unfair, is established.
A resource economy is not a utopia. It offers a solution to better understand the problems facing society without a mechanism for unscrupulous people to take advantage over morally just people. There will always be a dynamic change component within a resource economy, but the opportunity for change will not be hampered by a central authority or a horde of the ignorant population. The currency endgame does offer a utopia, of sorts, for those few able to claw themselves to the top of the pile. The currency endgame's peace involves termination or subjugation by force while the resource economy's peace involves freedom and the responsibility to choose for every citizen.
