As he describes it (emphasis added):
The libertarian movement is in a state of crisis. If we are to survive as a serious movement, if we are to continue to have any relevance, we must begin to advocate what Sean Gabb calls “grown-up libertarianism.” I prefer Rothbard and Rockwell’s term “paleolibertarianism.” What is a paleolibertarian?
A paleolibertarian is someone who believes in the rights to life, liberty, and property, but who is also mindful of the kind of environment required for libertarian philosophy to be fully realised. This environment is a homogenous society where the degree of time preference is low, and self-restraint high.
This is something that often gets overlooked or ignored in the discussion over libertarianism and a free society. In theory it is inclusive but in practice it is exclusive to that which does not require the state to exist or survive. There are many beliefs and ideas that theoretically do not require the state, but because they do not conform to the natural order of things, at some point they require coercion and aggression to remain.
Libertarians need to be cognizant of this. A liberty movement has to be centered around that which does not require the state and would be positively affected by its absence. Certain types of behavior, hobbies, preferences and lifestyles, although not prohibited by the NAP, would not last long in a free society. It can afford libertines and nihilists to an extent, but they would be minor aspects, not the centerpiece, of such a community.
Simply ask yourself: If there was no government how would (fill in the blank) be impacted? If negatively, it is something that we shouldn’t prohibit outright, but we shouldn’t celebrate or highlight as a way to attract prospective newcomers.
It’s why I advocated for a tribal mentality, focusing on creating relationships in an organic community. And if civilization is the absence of the state, the nuclear family is the bedrock of civilization, the greatest example of true anarchy in action. No free society can exist without it.
I also agree about the state of the libertarian movement. That’s why I’ve said that it cannot survive on its own. It needs to be cradled within the right ideologies that, while going beyond the NAP, foster the type of culture necessary to preserve it. People do not need to embrace these ideologies to be libertarians, but if they want libertarianism to survive, these are the ones which are most likely to keep it alive beyond the next 20 years.
