(a) Libertines (anarcho capitalists) differ from libertarians (jeffersonian contractualists), where Contractualist Libertarian = do no harm to the commons, and anarchist libertine = do no good to the commons. This is the underlying principle of decidability in libertinism (anarcho capitalism): avoid costs of physical, normative, an cultural commons, where the principle of decidability in libertarianism is merely the prohibition on the imposition of costs that would cause retaliation.
(b) no anarcho capitalist polity can form out of rational economic incentives because without commons and territory on low cost trading routes, any such polity must be endogenously parasitic.
(c) no anarcho capitalist can retain desirable, productive individuals in competition with other societies that do produce commons that add multipliers to the market for reproduction and production.
(d) any anarcho capitalist polity that did survive would be limited to endogenously parasitic members, and those polities that bore the parasitism would eventually, when in a period of stress, colonize, conquer, or destroy such a polity (pirates, drug dealers, money launderers etc).
(e) Ergo no anarcho capitalist society is possible -and its arguable whether one was desirable. If you need a nearly lawless borderland and will bear the costs to consumption of living there, then go. Antartica, Siberia, and canada contain vast areas of unused territory because it has not economic value higher than it’s costs of survival in harsh conditions.
The only possible liberty is that of the anglo saxons: contractualism. And the only means of achieving it is to eliminate demand for the state as a suppressor of aggression and retaliation by the use of the common law to prohibit the imposition of costs on life, kin, relations, things, built capital, norms, traditions, and institutions.
There is only one possible form of liberty then: the only social science man has discovered: rule of law, natural law, common judge discovered law, universal enfranchisement, and universal accountability, and universal reciprocal insurance.
