> The new developments have units stacked high and smashed together. It may not be absolutely dense, but it is certainly more dense than necessary or desired by residents.
Not desired by the people living there? Or not desired by other people in Dublin? These are two very different things.

Maintaining a certain amount of public space in the form of parks/playgrounds/plazas makes sense, but that shouldn't translate into shooting down high-density housing developments.

This kind of attitude -- the "let's keep it this way, forever" attitude -- is exactly why the bay area is now largely unaffordable. Sure, we'd all love it if we could maintain a certain neighborhood style AND have affordable housing. But we can't.
So, it comes down to what you value more: a style of neighborhood with more space between residents, or people being able to afford their rent without hour+ long commutes.
