I think power to execute is definitely a big part of it. A neighborhood can't afford a major work, or organize one, so it won't, but when a government entity can afford a major work, the neighborhood often has the power to stop that. Even though the major work is likely part of a larger orchestration of infrastructure, that one neighborhood can put a halt to it. They tried to replace a level crossing with an overpass in my city, arguably good for everyone. Well, they did argue it, and it didn't happen. Even though there is already a train line there, apparently an overpass was too much infrastructure for them.
