Wow that is twisted, with a lot of leaps.  I'll summarize with:  Liberarianism -> Power imbalance -> Institutional failure -> Fascism -> Authoritarianism
You can correct me if I misunderstood.

Let's say libertarism leads to power imbalance. How is it the case that such an imbalance leads to insitutional failure?  Maybe the power imbalance put the power into the most capable hands?

Let's say power imbalance leads to institutional failure. How is it the case that such institutional failure leads to fascism?  This is the biggest leap you are making IMHO.
