Author doesn't put enough blame on the built environment. If you have urban planning codes that require 2 parking spaces per dwelling and detached single-family homes, the area will not be economically serviceable by transit (nor will it be walkable). In much of America, car transportation is legally mandatory. |

Let's allow for a road that is legally 50 feet wide. Each house's share of that is half, so 25 feet. (it is 12.5 feet pavement and 12.5 feet curb/swale/sidewalk/etc.)
We need a 20x20 space for a normal cheap (no elevator) double garage. We want this home legitimately "detached", so let's allow enough room for scaffolding to stay within the property on both sides and the rear. That makes the lot 28 feet wide, and adding room for a staircase takes it to 32 feet wide. Including the half-street, the lot is 49 feet deep. That means 1568 square feet for the house.
At this size, there are 17780 homes per square mile. For comparison, we can fit 841953 homes in San Francisco. We can't just have homes of course, but on the other hand there will be more than 1 person per home. It happens that San Francisco contains almost exactly that many people, 884363 as of 2017. San Francisco also happens to be the second most densely populated large US city, behind only New York.
It thus works fine, or at least as well as the second most dense large city in the USA.
