From the comments here many many moons ago when he was still a PhD candidate in Political Science, (and followed this blog) Oren Litwin wrote this:
If the non-socialist end of the political spectrum cannot create a political philosophy that is both good theory and emotionally appealing, we’re doomed.
Any political philosophy that is not self-reinforcing is by definition not the best political philosophy. Libertarianism (with a small “l”) features a stoic acceptance of individual risk (i.e. the lack of government intervention) for the sake of long-term freedom and prosperity–yet takes no measures to ensure that the society educates its young to maintain that acceptance of risk. The equilibrium, if it ever exists in the first place, is unstable and will collapse.
This aside from the fact that libertarianism is emotionally cold and unfulfilling to most people, who have not trained themselves to consider lack of outside restraint to be worth cherishing.
Yup. We’re doomed.
