- We don't have carbon nanotubes long enough.
- We don't have technology developed for creating such a tether out of asteroid material.

No not necessarily. Yes, there would be more skyscrapers but there are a lot of places on Earth that are sparsely inhabited. Areas like Wyoming, mid-Canada, much of Russia, on seasteads, or undersea. Or perhaps in the deserts and the icecaps with domes over them? With vertical farming you can greatly decrease aridification and the sapping of nutrients from soil by overfarming. Requires little water, relatively few nutrients, and ends up great and disease-free. But only is this economical in a world where electricity is dirt cheap. You don''t have to see some weird Tokyo crap. And much of the world's population isn't in cities. OH YEAH, AND AFRICA!
