They all start with the idea of monetizing an underused resource (cars, houses, curbsides) with a novel business model whose goal is to dance around existing laws.

I don't know of a word that captures what feels like an arbitrage-ish assault on our law books. Without knowing that word I can only suggest something too generalized like organized crime economy

Houses aren't "underused" in many cities on Earth, there's simply a huge price discrepancy between hotels and Airbnb/residential rent. My landlord kicked me out[1] simply saying he's going to use it as an Airbnb instead. Even if he only rented it a few days a week it would be far more profitable, it was rough personally but I don't blame the guy. Holiday season garners absurd amounts in that area and would make a months worth of rent in a matter of days.
