The key is to build more housing units - if an area needs 50k more dwellings it doesn’t terribly matter if you build 50k luxury space apartments or 50k hovels - either is much better than arguing about it’d or decades and building nothing.
For whom? The locals who like their way of life selfishly don't want things to change. And unfortunately, the people who already live there are the ones who control whether or not new construction is allowed.
That would have been true if they didn't already spend those decades arguing instead of building anything which would theoretically reduce the general scarcity. It doesn't make it worth arguing over to the point pf delay now, but it matters that it's only feasible to build 50k luxury units by displacing the last hovels in the tiny amount of new space opened up for them since the 50s
