A suggestion for far future - your housing is where you would go to logout. Perhaps have a fast-travel menu, like when going from building to building. In the future perhaps this could be expanded upon and added to, but for the very basics, there would be "free basic housing" for everyone. A room in the city, where you would go to "logout", or else idk. Currently you can logout anywhere.. Not too much purpose (that i can think of) to housing except that i think it'd be cool.
I think there are others who are interested in future housing, if you could share your ideas, I'd like to hear them myself.
