alt Hacker NewsAt the density of Kowloon Walled City, the entire population of India could fit within the city limits of San Diego. Nobody is asking for that, silly.
We could 1.5x the density of San Diego and still have the livability of Copenhagen. We could 3x the density of San Diego and still have the livability of Vienna. We could 5x the density and still have the livability of Paris. 8x and still have the livability of Tokyo. We have a ridiculously low bar to pass, all we have to do is allow it.
Paris [1] and Copenhagen [2] have similar housing issues. Both are some of the most expensive cities in Europe [3]. Vienna has a large municipally owned and non-profit housing stock [4]. The situation in Tokyo was okay while it was growing its stock like crazy, it is facing an intensifying affordability crisis right now [5]. If there is a bliss point at which the housing crisis is solved with density before Kowloon Walled City levels, it surely not at Tokyo levels. What do you think that bliss point is? Why do you think it is a better solution to grow city densities to those levels rather than trying to make it easier to live and work in compact, mid-rise 15-minute cities that people generally seem to prefer?
