There must be already a name for this particular fallacy, when a bunch of people considered themselves "knowing the [only] right direction" and especially "destroying and discarding everything to build it up from scratch as they know will be the best for all". A-la those uneducated, ignorant, but cook-sure and self-confident lower-class revolutionaries in Russia hundred years ago who were unable to grasp that "evolved [social] system" has some subtle "laws , forces and reasons" behind it and that uncomprehensive, even unreadable philosophy or a naive, oversimplified model [of economics] is much worse than no philosophy or model whatsoever. Self-regulated (and especially evolved) complex systems are "smarter" than any bunch of individuals ,)
