Well articulated. I'm not from the US, but I've seen housing developments go sideways when they built four 10-story blocks (not in somebody's back yard, but in an area without proper infrastructure) and after 1000ish people had moved in there were 1 hour long queues just to get out of the complex because there was only one road with one lane per direction. And the only bus stop was not really reliable.

This was not built in the middle of the city because of land availability (and huge prices even if there was land available - you're near the metro and tram and a bus stop? pay 50% more. oh, you're near a park too? pay 50% more on top of that). Should we just tear down old buildings in low density areas in the city to make room for big blocks? Some might be worth tearing down because of age and overall condition, but good luck getting people to move out.
