Musk might have a point -but he's got his own blind spots. Sky scrapers create efficiencies by packing large numbers of people densely- they all have to go to one place, but in total they take up less real estate. Musk's contention is to transport people to these highly dense areas, rather than increasing the density of the vehicles we transport people in turn, instead we stick with low density vehicles, but do far more journeys. It'd be like having a city where all the offices are sky scrapers but all the houses are detached bungalows. It'd be nuts. As office buildings get bigger and more efficient you get housing blocks that are bigger and more efficient and you get transport that's bigger and more efficient - trains and buses, not just more cars and more roads.
