I'd still make the same argument about specialized economies and resilience. The path of least resistance leads to specialization and loss of resilience, and then when the path of least resistance leads to the coal mine, Ford or Walmart to pack up and leave you have a huge problem.

So clearly just because the market is good at picking out the path of least resistance doesn't mean the market is best, or even good.

A society committed to the notion that government is always bad will have bad government. And it doesn't have to be that way. — Paul Krugman
