Have you not travelled before Airbnb is a thing in a place? There were always similar alternatives?
The blame game with Airbnb is the most ridiculous thing ever.
Completely unfounded to try to blame so many things such as the housing crisis. Oh, that is just Airbnb. Just ignore that you still have problems due to taxes, government policies in places where there's virtually no Airbnb offera.
Hotels being regulated generally means nothing in places where there's a lot of tourism because you still get extremely poor services and experiences at times and Airbnb and other similar BnB services (this is not new, come on, is everyone <30 years old?) have provided much needed competition improving quality, which has otherwise been going downward steadily (cleaning, breakfast, bathrooms, etc).
You seem to dislike supply so youd problably want to ban low cost airlines so that less of the "rubble/mass tourists" would travel, right?
