The only thing i can see on the right bad is that many people dont like beeing cramped in with many other people. + want to have a garden Balcony can be a "garden" but not as good. I have nothing against the right, but keep in mind not everyone is the same.
Right - unless you're getting a custom home, builders do jack shit about noise control - at best, you'll have some fiberglass batting inside an interior wall, but even that is usually not done. Take the same kind of standard cost-cutting and apply it to an apartment complex, and congratulations, you just created the projects. My point being is that if residential density is a desired social policy, then there need to be standards put in place that focus on quality of life, not just safety/environmental standards. But builders and developers have regulatory capture (in the US), and things like "quality of life" are marketing premiums rather than something everyone should enjoy.
Buildings like the one on the right near me have something like community gardens, but exclusive to the residents.
I don't know exactly how it works, but it seems residents who want a garden have one, and those who don't aren't forced to maintain exactly X cm high grass.
