I believe that humans in large societies have two natural desires that frustrate libertarians.
1. A desire for religion, defined as a set of rituals, norms, and affirmations that are shared by a group and which the group believes it is wrong not to share. Thus, rooting for your local sports team is not a religion, because you realize that it is not wrong for someone else not to root for your local sports team. But if you are against GMO foods, then you believe that those who disagree with you are wrong.
2. A desire for war. I think that it is in human nature to fantasize about battles against tribal enemies. War arises when those fantasies are strong enough to drive behavior. People who have recently experienced war have mixed feelings about it. Some want revenge for defeats. Others are sick of war. The sickness of war often dominates, but not always. If there has been no recent experience of war, there is a gradual loss of the aversion to war, and war becomes more likely. Peter Turchin takes this view. Incidentally, Robin Hanson recently binge-read Turchin. I think that the way to read Turchin is to view his thought as 95 percent intuition/theory, 5 percent empirical analysis. Turchin himself would prefer you to believe that he is much more driven by empirical analysis.
If these desires were to disappear, I believe that humans could live without a state. However, given these desires, the best approach for a peaceful large society is that which was undertaken in the U.S. when it was founded: freedom of religion guaranteed by the government, and a political system designed for peaceful succession and limitations on the power of any one political office.
At the moment, I fear that the anti-Trump resistance strikes me as having the characteristics of a religion whose followers are fantasizing about war. Perhaps there is a symmetry on the other side, but it is dampened by the fact that when you hold the Presidency you can get your way peacefully (if coercively).
I think that it is fine for libertarians to warn of the dangers of religion and to oppose war. That is what I am doing here. On other other hand, when libertarians assume away the desire for religion and war, their thinking becomes at best irrelevant and at worst nihilistic.
