I think existing communities is interchangeable with incumbent residents. There are probably better ways to protect mass displacement of low-income residents since rent control only applies to certain really old buildings. Preserving the community in itself is not a bad thing to do but a lot of these policies have also been blocking the building of higher density housing, which could satisfy everyone (keep old residents AND let in new residents).
