I can't quite imagine how hotels would work then. Generally, you'd say "Oh, we'll make an exception for them" but then many people would try to skirt themselves into the exception.

No, serious question. Just wondering what world was being envisioned.

Not everyone wants to buy a house - if I know I'm only staying in an area for a year or two, I wouldn't want to go to the hassle of buying and selling a place. Or if I move to a new area, renting for a while until I decide where I want to live longer term is a useful tool.
