@nullpointer and honestly brother, there is probably not one sentence you said there that I could possibly disagree with. I believe the ideals of libertarianism are quite beautiful, I just don't know if we could ever be stronger than the people holding the guns.
Maybe I'm guilty of not having enough faith in humanity, maybe that is my biggest flaw as a person. It can be quite easy for people to abuse power, that even when a social structure has started with a positive/ideal goal eventually greed and corruption show their face.
But again, I may be guilty of not having enough faith in us humans, but it also might be a good sign that I'm here, learning a bit more every day.
A "libertarian utopia" would still require a monopoly of force to keep the poor separate from the rich, otherwise the poor would eat the rich via revolution when the class divide became too wide
