1. That's a poor argument and completely irrelevant. There's a massive difference between short term and long term lets. AirBnB has more short term rentals available than long term ones in the entire country. That's a problem even if it's a 'subet' of all available properties.

2. Oh they pay a little in tax. Not the same as depriving locals of places to live near where they work affordably, and pricing all but the highest earners out of a home in general. Not to mention it pushes locals further and further out of the areas near jobs, and even then it's more and more expensive. Longer commutes, higher rates, it's all a net negative on the actual residents of a city. Nobody benefits but the entitled tourists and the rich landlords, who are insulated enough by their money to not see or care about the societal harm they cause.
