I think libertarianism is an ideology that says that people have the right to take responsibility for their own lives and make their own decisions for themselves without getting anyone's permission. That's what I see anyway. I could be hyperbolic and say something like "it's nice that you think human beings are stupid and need a mommy to make all their decisions for them" or "guard rails can be used to lead cattle to slaughter" but I think you just genuinely believe the second point you made. The world might not be simple, but I think humans are perfectly capable of navigating the complexity on their own. That's really the crux of this disagreement. It's an ideology that says human beings are very capable and good when left to their own faculties the vast majority of the time and that it is ineffective to take away their right to self actualize in a failed attempt to try to prevent the instances when that is not the case.

Side note, dunning Kruger has been discredited as statistical bias, I only know because I see a post about it on this site almost once a week.
