People in cities and colleges have done that for decades. Not just "roommate" in the Friends sense where you have 2 people living in a 2 bed flat, but roommate as in sharing the same room - indeed 20 years ago I knew of some places where there where 5 people sleeping on 3 single mattresses in a single attic in London, with nuclear-dub style bunk sharing.
Demand for what people want (a place to call their own without having to live with strangers) is far in excess of the supply, and has been for at least the 25 years I've been an adult.
