The surprised reactions from airbnb taking up housing stock are from people who don’t piece together what you describe. Basically if the airbnb is taking needed housing stock, why not just zone for more housing? Or regulated hotels that these days are able to compete with airbnb on cost once again? That’s never mentioned though, people just stick fingers in their ears and repeat “screw airnbnb” without thinking of penciling this sort of stuff out to its logical conclusions.
