You miss a huge issue in your analysis: Airbnb rentals are Second places to sleep every night, like hotels. They are vacation rentals. In other words, for almost every AirBnb bed, there is another bed elsehwere in the world lying empty. So people don't get to sleep in these beds otherwise. And this of course means that it's the less-well-off who suffer. And the benefits go to those who can throw their money around, to the detriment of basic human existence.
