(Profoundly Important Concept)
The Westphalian peace was a unique western invention making STATES accountable for their members. Individualism = Statism.
States created individualism. Throughout all history groups have been accountable for the actions of their members.
Families, clans, tribes, nations.
To do otherwise is to force the host population to bear the cost of domesticating a culture.
One cannot advocate individualism without advocating statism, and the export of costs onto host communities.
There is a reason authors of libertarianism were from disaporic tribes not land holders that had to pay the high cost of holding territory against invaders.
