He was a man who believed in non-intervention, non-coercion, non-violence in the era of the Cold War.
If pure non-coercion produced such efficient results, why do firms not expect their employees to spontaneously organize to produce more efficient outcomes than top-down direction?
A libertarian society bases itself on the rule of law and more fundamental to that on the principle of an individual's liberty limited to the non-coercion of the other!
For what it's worth, I'm experimenting with words like "tolerance" and "aggression free" and "cooperation" with respect to ideas associated with freedom, non-coercion, division of labor, and trade.
