I disagree. Amorality in an economic system encourages things like Martin Shkreli, and ignoring externalities like pollution, making life worse for everyone else for the benefit of a few.
"Making life worse for everyone else for the benefit of a few" is the inevitable result of any policy that places upper bounds on consumer preferences and transaction opportunities in a market. It is the imposition of a morality that leads to fragility, since the morality in question is almost invariably in favor of the statesman and the businessman.
