> We need mixed-use developed walkable neighborhoods. We need our work places to be mixed within our neighborhoods along with our parks, convenience stores, and everything in between.
I strongly endorse this. I'd argue that it's totally compatible with expanded housing, though.
The population density of Somerville, MA is 18,000 per square mile. It's the 16th densest municipality in America, only narrowly behind San Francisco itself (18,600). That's almost 3 times Berkeley, CA (6,400), and 7.5 times Palo Alto, CA (2,400).
Somerville is also a pleasant, human-friendly city devoid of skyscrapers. It's a perfect example of mixed-use urbanism. The tallest buildings are ~12 stories, and that's government housing on the edge of town - almost everything is far shorter. That's nuts - it says we can massively increase population density while maintaining a Strong Towns approach to urban design.
Somerville cheats a little bit, because so many residents work or go to school in Cambridge and Boston. (Workplaces obviously kill density, since they're sized per-person but exist parallel to residences.)
But Somerville's real advantage is being old -
older than stupid zoning laws. There are only 22 residences in all of Somerville that would be legal to build today, despite those old, illegal residences being livable and massively in-demand.

I don't think there's really a dichotomy between "live in NYC/SF style skyscrapers" and "overpriced housing with urban sprawl". You can relax zoning restrictions without getting highrises and tenements. It just requires careful planning and a willingness to abandon suburban, parking-lot filled design.
