I agree. If a large number of residential spaces start getting occupied for AirBnB usage, that makes the housing stock that much shorter. And that would actually increase price of housing in the city. As another commenter posted, it was harmless when people were letting travelers stay the night in their currently occupied homes, as that didn't decrease the housing stock. But when people start using residential properties as fully functioning motels, that's when we see society adversely affected.

And this is a far more logical argument than the Brothrel one as not everyone agrees how bad that is.
