Noise, litter, etc, "nuisance" laws are on the books, but mostly depend on people following them voluntarily. The local authorities don't have the time/staff to investigate and resolve them all the time.

... but the customers of these Airbnb rentals are not. :-)

that's the point of the regulations...

People support anti-pollution measures yet corporations still choose to pollute. Curious.

That’s a false analogy.

You have two parties who want to enter into a contract and a third party unrelated to the contract that doesn’t for whatever reason. Just based on contract law and common sense the unrelated party shouldn’t have standing. Now if there’s externalities to the contract that impact that unrelated party sure, but only insofar as to get those externalities addressed.

This is not the same as a robbery which involves no contract or a willing counterparty to the robbery.

Yeah, IME, if the guests of the rental acted exactly like locals, and the units were not removed from the local housing supply (not sure how that could be), or the local housing supply was in excess to the needs of the population (not sure where that is), it would be fine.

I don’t understand why the local housing supply is privileged in your scenario. And if the local housing supply is a problem it’s one the locals created themselves so…

You believe that the local area has no standing, that's incorrect. Laws and regulations are third parties impeding on the contract all the time. Libertarians may dislike this, but it's one problem with democracy - the majority make decisions you don't like.
