I see nothing wrong with old (or young) folks who are alone and have no family sharing the same house as roommates. Not only will they have company, they'll be able to share expenses. It's sure better than having to get 200 cats for company.

Yeah, but how often does it happen? You may notice that by the age of 40 or so, most people are so set in their ways as to make living with someone else difficult to say the least. And they get more set in their ways and difficult as they age--particularly if they've never had to be considerate of another human being sharing their living space before.

Not a practical reality. It's hard enough to live with the person you're sleeping with. Take away that intimacy, and living with roomates or family becomes more of a hassle than it is worth for the average adult.
