It’s a matter of perspective and use — high density one place means you can have open space somewhere else, for a given amount of land.
I’d much prefer a few large dense housing complexes, surrounded by green space, than suburban sprawl.
I’d also prefer something denser than suburban sprawl, but I think there’s a balance point between that and what the post is showing.
I think that 3-5 story apartments with shops underneath are the best ones, because they aren’t too dense while also not wasting space.
Make those with decent construction so every cough and sneeze isn’t broadcasted to all of your neighbors with good design so it’s disability friendly, and that is the dream right there.
