To be clear, my point isn't that central planning is good. My point is that people may prefer centralized control for certain things even though they understand what non-directed processes can accomplish. To use the author's example of the post office, there may be reasons why one might want the post office to be a public entity beyond "only government could build such a complex system". For instance, it might be reasonable to wonder whether a postal system that evolved organically would cover everyone in a society, or would rural people or others who are expensive to reach be left out. Mail delivery probably qualifies as something we want everyone to have access to in order for a lot of our systems to function.
