This is a very online oriented debate. Derek Thompson might hear mostly from left coded anti-trust types on twitter, but I really don't think that's the main opponent to abundance.

If you spend time in the individual communities where this battle happens, the voice of the classic NIMBY (worried about property values and crime) drowns out the left-NIMBYs that worry about "greedy developers" and gentrification. At least that's been my experience in West LA. Many of the less-online left critics eventually come around to realize that upzoning type solutions and public housing type solutions aren't actually in conflict with each other even if they disagree on relative priority and impact.
