This overlooks that roads take up space and other resources. If you build or expand a road, that's something else you can't build or expand (housing, offices, parks, schools, etc.) there. Moreover, who wants to live next to a busy freeway? Noise and air quality aren't great. In the 1000 lane situation, people can get where they want, but where is it that they're going to if the fraction of space is mostly roads? You can see the practical limits of pushing for more, wider roads at scale clearly in Los Angeles. A massive grid of wide freeways. Long commutes. Bad traffic even outside rush hour. Auto dependency. Air pollution. High household transportation costs.
