I never really understood the economics of public restrooms in America. Who pays for them?
Americans. The same population as most of the beneficiaries.
Thank these folks: https://en.wikipedia.org/wiki/Committee_to_End_Pay_Toilets_i... - the road to hell is paved with good intentions I suppose.
You don't get arrested for public urination. You get a citation, if you are drunk they might haul you to the jail for public intoxication, but you are out when you sober up.
As long as you don't pee near a school and what not you should be fine.
Local sales, income, and/or property taxes.
Municipalities, counties, state, and the federal government all have the power of taxation in the US.
Everybody poops; shit happens. The only real question is: Where does this shit happen?
But to answer your question, public things are paid for by the public.
Many transit centers are owned and operated by a municipal transit agency and typically have restrooms, especially large airports and train stations.
Public rest areas are pretty common along major highways and these include restrooms.
Publicly-owned parks usually provide a place to poop, too: Sometimes it's an installation with composting toilets, sometimes it's just a seat over a septic pit that needs pumped out periodically. Sometimes, it's fancy with flushing toilets and sinks for handwashing. Other times, it's just a rented portajohn (that may be full of spiders and smell like death, or be very tidy). And sometimes, they're locked at night when the park is closed. But -- usually -- public parks of any substance offer something for facilities.
Just last week, I worked next to a public park in a very small town (population ~2,000) with some well-maintained basketball and tennis courts. There were a couple of portajohns present. (I did not investigate them further.)
And when there's a major events that draw crowds, like our very public fireworks displays in downtown areas: Temporary restroom facilities are provided.
What we don't have very much of here are permanent, literal-public restrooms in the denser parts of cities. That is very problematic, but it is slowly improving[1].

You've never been to the beach, a city park (or state or national park), a highway rest stop, or any of the thousands of other places public restrooms exist?
What a weird take...
I was also not considering things like port-a-potties during public events, since i was only considering permanent structures.
Almost like an airline bathroom size - might be a bit claustrophobic but these are for emergencies and space saving would be big.
the doors could be wired to sensors that are connected to a central network that shows in real-time the availability and also some alarms if something is out of the ordinary etc.
how about some of them being ADA-conforming, with maps noting where they are?
