Your complaint that libertarianism didn't provide you something to tide you over when rationalism fails, sounds like the libertarianism you were seeking was a church, and when it didn't live up to the full church role you had hoped for, you jumped out and into something else that provided for that need. Most libertarians have many different things going for them in their lives, that they can draw upon when they "face the occasional emotional pits of life." I can't imagine any libertarian looking for that kind of help from the movement, a golf league, chess club, music band, an arts association, or even a baseball team.
I don't know any monks in the Almighty Church of Libertarian Holyness. But if you were a member of that church, actually thinking it could accomplish as much, then your rationality was not very sound to start with. But don't cast the rest of the movement into the utopian dreams you had, which required monk like robots with perfect rationality. This is a movement and philosophy that encourages individuality, and self ownership. The exact opposite of what you have conjured up in your mind.
Libertarianism is an opposite of utopia. Those who don't understand the philosohpy, continually expect us to live up to some utopian ideal, having answers to every imaginable problem under the son. Sorry to repeat the most often quoted libertarian saying; "Utopia is not an option."
FR is full of them.
