Ok, well surely you recognize that there are lots of people who agree with me - who feel single family homes are nice and living elbow to elbow with your neighbors in maximum density is not in any way desirable.
Unfortunately, ultra-urbanist zealots are very loud online. I suspect many of them will change their tunes with age.
Edit: what’s damaging to the ecosystems of our planet is PEOPLE! There’s no law of nature that states a suburban density isn’t sustainable, just that it’s unsustainable for 8b people. You’re proposing eco-austerity because human population is out of control
