That's an interesting history, but you seem to be focused on libertarianism as an economic doctrine, whereas I see late-modern libertarianism as a toxic form of a broader ideology, namely of liberalism and ultimately of individualism, which go back to John Locke and Martin Luther.

I agree that political systems have a Marxian impact on political and other mainstream ideologies, but I don't see why that impact should exhaust our cultural capacities. Again, culture is impacted also by other aspects of history, and those form a continuum that stretches back for millennia.

You seem to want to explain too much in relatively limited (i.e. narrowly political) terms. Or maybe I'm not understanding your framework. How, for instance, would you see the relation between libertarianism and classic liberalism or early modern individualism?
