>I really don't like the idea of stamping out all single family homes and nice green areas in proximity to cities.

I don't think anyone seriously wants to replace every single family home with something more dense (even if the rhetoric indicates so). It's harmful and unnecessary. E.g.:

* There is an estimated 3-4 million housing unit deficit in CA, on 14 million total units (US Census). We'll take 4 million units to err on the extreme case.

* CA currently has 7 million single-family homes (US Census)

* Assuming 100% of that deficit is made from replacing a single family home with a quadplex, it would take 1.3 million single homes -> quadplexes to make up the 4 million unit deficit.

Even in that most extreme case, I can't imagine one quadplex per block would affect green areas or the totally legitimate choice to live a single family home.

In reality, I think most YIMBY advocates want mixed-use medium density, which requires an order of magnitude fewer buildings.
