So the space elevator in 2e has moved to Pavonis Mons, which makes sense given its more equatorial position. The city of Pavonis is a carbon copy of 1e Olympus: space elevator, largely depopulated, and with lots of poverty.
It seems a pity to just have the tallest planetary mountain in the solar system sit empty, though. I see it as a place where the filthy rich have their equivalent of country estates. Sometimes you just have to get out of the city and get some space, you know? Space where you own everything and everyone around you and still have all the luxury you are used to and all the guards you need to keep you safe. Where you can do pretty much anything you like and you're not held accountable for your actions by anyone but your similarly Croesus-like neighbours.
The roads that lead up here are no longer used: after the heavy construction of the bulk of the estates they weren't maintained and the winds have worn much of them away. There never was a maglev rail line that ran here; that's for peasants and the clanking masses. These days pretty much everything has to be flown in. Keeps the riff-raff out.
Sure, it's out of the way. Sure, it's ruinously expensive to run everything in such a remote location and thin atmosphere. But that's the point.
