Well Mises did say that sometimes you need a little fascism to keep the lower orders in their place.What does warrant a mention here I think is The Churchill Memorandum by Sean Gabb. This novel basically depicts a world where World War II as we know it is avoided by Hitler and Churchill dying. Nazi Germany is taken over by Goering who goes neoliberal (I'm not even kidding-he relaxes the Nuremberg Laws and implements Austrian economics on the advice of Hayek and von Mises, which are credited with boosting the economy) and both Britain and Germany are semi-aligned against the USSR. In-universe, this is treated as almost a good thing as the bloc stands against communism. Oh and Britain is still a powerful empire which also appeals to the so-called 'libertarian' author.
It cannot be denied that Fascism and similar movements aiming at the establishment of dictatorships are full of the best intentions and that their intervention has, for the moment, saved European civilization. The merit that Fascism has thereby won for itself will live on eternally in history.
