There's also well meaning but poorly thought out activist maximalism. Like blocking new construction of a building on say a former McDonalds site that will be 30% low-income housing. The activists demand it be 50%.. 80%.. 100% or don't build.

The delays/fights also may deter developers in that neighborhood generally. Meanwhile - how much low-income housing did the former McDonalds provide?
