That’s very funny. It’s funny that you think that’s impressive. It’s funny that you think density means anything. It’s funny that you think you actually have experience because others did the work. It’s funny that you think your lame 10x density increase can actually translate to a city like Los Angeles, NYC, San Francisco, etc. It’s funny you can’t connect reality to math and understand what you are talking about is pure fantasy: NYC 20MM today, 200MM after your fantasy Los Angeles, 12MM to 120MM Chicago, 9MM to 90MM Etc. Please. Get real. Now, if you are talking about building where there’s nothing (3000 people per square mile is nothing), well, have at it. That’s not where housing availability is a problem. Oh, yes, your attempt to use density to impress is hilarious. I did note you said “your neighborhood”. One or a few apartment buildings can easily cause a 10x density increase in a neighborhood, given that “neighborhood” can be just a few blocks. If you actually want to make the point you are attempting to make, provide links to the many stories that would have been written about a non-trivial CITY increasing the population by a factor of ten within its own boundaries. Otherwise, I think you are trying to inflate two apartment buildings into something they are not. This is about providing affordable housing for tens of millions of people. That cannot be done within the boundaries of major cities in the US. That problem is asymptotic.
