I do believe that the pessimistic economic view Hayek espoused is still quite capable of holding its own regardless of whether or not his ideas on economic cause and effect towards tyranny would. One doesn't even have to speak in the language of economic freedom, but simply the language of complex mathematics to see why having a direct economic link between millions of buyers and suppliers is generally preferable to replacing them with a handful of economic transactions handled between a relative handful of participants operating at or near the top of the hierarchy.

As for trying to psychoanalyze the man well post-mortem and draw conclusions from that with which to criticize the work as a whole seems to be the most indirect path and the one most fraught with prejudice on the part of the one psychoanalyzing. If the theory can so easily be debunked, best to stick to the substance rather than the man, correct? We have the man's words, but not his mind.
