This is interesting although a couple things raised questions for me. One, I am not convinced by the arguments like "modernist architecture didn't become popular until after zoning". I do not think that people in Chicago were making decisions based on zoning in Boston. For this argument to work, I would need to see more specific evidence that for each of a number of cities, downzoning in an individual city took place before modern architecture began to make inroads in that city. Also, ideally this would not be about "modern" architecture but just about "buildings that people thought were ugly". Second, the article makes several references to how lots of buildings were torn down and replaced throughout history, but we only see opposition to it more recently. An obvious explanation for this is that it is only relatively recently that democratic decision-making (including at the city level) became widespread and entrenched enough that individual citizens could influence such matters at all. Until relatively recently large-scale development was often a matter of backroom negotiations between politicians and wealthy developers who ran roughshod over the wishes of ordinary folks (and before that it was even worse, for instance in systems where most land was owned by nobles). The NIMBY movement can be seen in part as a reaction to this.
