Sure, some people might like living in a huge apartment that takes up a whole commercial floor, but how many can afford it? The landlord isn't going to rent out that much floorspace cheaply, and even if they did, can you imagine what the electricity cost for HVAC would be? We've seen this kind of living arrangement in the Blade Runner movies (J.F. Sebastian lived in some old hotel I think, and Deckard in the newer movie lived in a casino I think), but they presumably didn't have to pay rent, and they probably didn't have any heat either. They also lived alone and didn't have families complaining about it being too cold inside. I suppose you could put up some insulated walls (if they aren't already there) and make a smaller apartment within the space where you keep the HVAC on, to keep your energy costs manageable, but then you're back to the previous issue about the cost of rent, because of the sheer amount of floorspace. If the location is desirable, it's going to be too valuable to rent out at the price of a normal apartment.
