People who realize that not all places that need more affordable housing have space to build more housing, and that prices are inflated because of landlords and companies buying up the limited property. Like in cities.

Different situations, different priorities.

NIMBYs whose main complaint about short-term rentals is the (admittedly significant) nuisance factor of having a "party house" next door... but also don't want a duplex or other multifamily housing arrangement across the street, where it might bring The Poors into the neighborhood and drive down their property values.

Fact is, though, that most Americans are in debt up to their eyeballs, and their financial situation only works out if they think of their house as an eternally-appreciating asset that they can continually leverage to pay off other debts. If the line ever stops going up, they're fucked. I hate NIMBYism, but we've made our society into such a hypercapitalist hellscape that on some level it's hard to blame people for it.
