I have 2 questions: (1) Do not such articles sound like "not everyone can afford a holiday in Hawai"? Or "all my friends have a Mercedes AMG but I don't"? What is the difference? * (2) In Bay Area, the daily commute itself is an obvious sign of overpopulation. How does more housing not make it even worse? * I exclude the gentrification problem which is really affecting the lives of poor and old people as their mobili…
It would be useful, for many reasons, to have a greater proportion of people living in cities. So, it's useful to challenge your implicit assumption that doing so ought to be a luxury.
(2) In Bay Area, the daily commute itself is an obvious sign of overpopulation. How does more housing not make it even worse?
a) The commute is awful because the Bay Area is overpopulated relative to its transit infrastructure, not some natural limit. Or, conversely, the Bay Area's transit infrastructure is under-provisioned relative to its population. Faster, more extensive transit infrastructure can drastically improve the commute at both current and higher population levels.
b) We also underutilize the land close to commute destinations, so everyone (but the residents of single-family homes near downtown) has to travel further than they should. Pedestrians don't need much in the way of infrastructure (just sidewalks, which most of SF already has). Building more residential skyscrapers in the midst of business districts lets more people walk to work in a short time. Building more mid-rises (~6 stories) where there are currently single-family homes gets more people into commute distances that are reasonably quick on a bicycle, motor scooter, or public transit. Density of residents also promotes density of stores, so that i.e. everyone can be a short walk from their grocery store, rather than needing a car to shop, and the reclaimed land previously dedicated to parking can house more people.
