Well, the free market is a sort of solution for the well-off. How would you then suggest dealing with the riots in every US city when the poor can no longer fuel their cars? Some sort of Mad Max 4? Just curious.
As for the free market - is it really a universal tool, fit for every job? Screws and bolts are superficially similar but need entirely different tools to tighten them. Free markets simply don't work in every case, you need regulations. Air (and air pollution); hunting and fisheries; building and zoning regulations; water; food (in the UK) in WW2.
The prediction of a "Mad Max"....post-apocalyptic societal breakdown based on vengeance, and, murder.... is a far left, elitist scare tactic to grease the skids for an..."Earth Should Be Fair"..."Darkness at Noon"... "1984"....future.
