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.
