I must say that while I don't consider myself sympathetic to Libertarian ideals, I find your thoughts, experiments and models very intriguing. Thank you for sharing this. As someone who is trapped in the corporate rigamarole for family and financial reasons I found your comparison of communistic centrally planned economies to corporate processes and organization and the shared dysfunctions to be enlightening.
I must also say that I agree with your assessments of the failings of our modern capitalist system and how governmental policies foster monopolies. A market based system with tougher anti-trust regulations could be a potential solution for this and one I would get behind.
On the whole however, it is not logic that makes me skeptical of this as a long term solution but my lack of faith in human nature that such a system could remain uncorrupted. Human nature is such that we present gradual entropy into such a system until it decays into corruption and dysfunction. While human beings as a class will present ignorance, greed, corruption and decay, it is certainly a safer and easier task to find a strong, intelligent, benevolent leader that can achieve all of the goals of the complex system.
Competent totalitarianism I feel is the best that human beings can hope to achieve in a world before post-scarcity. There are a number of such examples throughout history where centrally planned leadership when competent can be HIGHLY effective. Robert E. Lee and his outnumbered, outgunned army nearly winning a statistically unwinnable war. Alexander the Great, a near child, leading less than 50k phalanxes and conquering most of the known world. The pharaohs of ancient Egypt engineering and building a monumental tomb that stands to this day. The United States sending a group of men to the Moon and back.
If such an exceptional authoritarian figure had supreme power and wealth then they would be uncorruptable as there is nothing any of their subjects would have to offer them. They would be an exceptional statesmen or even an exceptional economist out of the passion of the craft. This I believe is the only hope for humanity since there is a statistical percentage if such a person were chosen at random from a pool of competent peoples to fill that role then there is a statistical liklihood that this person might be a huge success and advance humanity. Compare this to the statistical liklihood that a well regulated free market system will eventually erode into corruption, monopolistic control and entropy, 100% of the time according to human history. Only a neo-monarchy can save us.
