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.
Population density isn't a great measure here either, because Dublin has a ton of open/protected/unbuildable space, and even the planned communities have a certain target ratio of public/garden/playground use space.
I think it's more a case of it's the 'burbs, and they'd like it to stay that way.

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.
That's something to be careful with too. I certainly desire a couple of acres of rolling woodland in Palo Alto, but... yeah, that's probably not in the cards. Some people may not desire dense housing, but given the alternatives like moving back to Cyanide Springs, Oklahoma, they might find it's still ok.
