For example, it is the nature of man to be . . . gregarious . . .
Dang it. A major stumbling block to rugged individualsim, is it not?
No. I do not know what you mean by "rugged individualism". I am writing in regard to the political philosophy of individualism --not simple social interaction.
By the way, you could have an island filled with thousands of political individualists and they would engage in robust and healthy interactions forming and disbanding temporary associations, establishing and participating in organizations --social, economic, and political -- and in so doing, never violatethe Rights of each other.
In contrast you could put one peasant and one worker on the island along with collectivists Mao, Engels, Marx, Galbraith, Woodrow Wilson, FDR, Hillary, and Kucinich, and they would be tearing at one another's throats to see who would be the one to control the lives and actions of the peasant and the worker.;-)
