I'm confused as to how you think libertarianism is the path to get to that society, the only path, or even the best path. If we are dreaming futures, the goals you mention could just as easily be met by a system in which super-sentient AIs plan all the details, and robots provide all the labor. After all, the only monetary 'freedom' that is better than having complete control over one's money, is the freedom of not having to even worry about it.
