Sure, but what I'm saying is that it's not as simple as a function that moving people closer together is infinitely scalable to lessen our impact on the environment. There's no free lunch. That's why I think upzoning to medium density 15-minute cities is the best of both worlds. Not to mention that living in a dense urban environment has a worse quality of life for a lot of people - that's why people don't want to do it. They like the space.
