The obsession with efficiency at the cost of other, far more worthy virtues is what has brought us to this point, where "efficient" global supply chains cannot now produce urgently needed goods at a time of crisis.
Supporting "worthy virtues" is all well and good, except that it's subjective and not always well thought out, leading to unfortunate consequences.
I'm sure plenty of people thought it great to help Sally Struthers feed the 3 million starving African children in the 80's...until the result was 10 million starving African children.

Having many competing businesses does not ensure these other virtues arise. Having a mechanism whereby the better businesses rise make it more likely they have the income to explore.
