Is it though? If we have a thought experiment of a donut of mid rise 5 story apartments powered by its own footprint with a central park a couple km across and possibly commercial activity and outlying farms vs one colossal skyscraper in the middle. The donut has less transmission infrastructure (most of the energy travels under 100m). The food is less centralised, people could even go and get it from where it is packed on foot with no transport step if you wanted to go to the extreme. Each floor of the apartments is holding up on average 2.5 floors above it so doesn't need to be as strong. It takes less material. The center of the donut is free for other uses rather than needing to be entirely transport infrastructure to get people in and out. The donut has a better exposed surface area to volume ratio (unless the majority in the skyscraper have no windows or is made from impossible materials and doesn't taper) so needs less heating/cooling. The donut has more thermal mass available for heating/cooling loops so doesn't need some higher tech thermal store. Less energy is needed for water and sewerage per person. Maybe 10 or 20 stories is optimal, maybe it's 3, but the peak isn't at the as big as possible skyscraper end.
