People also need to learn that vertical doesn't mean high rise apartments. There's a big gap between single story detached houses and high rise apartments. Townhomes, condos, row houses, and so on can all fill that gap.
Vertical still means “close proximity to neighbors” which is what a lot of people object to when it comes to urban living. I will never again voluntarily live in a building with a shared wall or ceiling.
Same here. This is exactly what I don't want. Sure you can cram a lot more people into a smaller space and make it cheap if you want, but it causes more problems than it solves. Maybe in some futuristic utopia this would work, but not in this reality.
