Well, that was the point of my irony. I agree with you that libertarianism (whatever that really is) will naturally evolve into a "rightwing, highly conservative monarchy", unless some comissariat prevents it.
The philosophy of freewill is not tied down to any current dogma, and what may be the current natural outcome of the current dogma is not absolutelisticly definitive of free will. Time will bring progress, and your commissariats won't prevent it. Monarchy will not continue to be natural outcome.
