I think there is a demand for more public toilets almost everywhere, but public urinals aren’t an answer to that. They’re an answer to the people who go ahead and piss on business owners’ premises / within tourist sightlines, and by definition, they find it convenient to piss in the open.
The moral isn’t so much that local governments only want to serve (a subset of) men; they don’t want to serve anyone, but if you force their hand by using the whole world as a toilet, and leaving them to clean it up, they will grudgingly and narrowly accommodate you.
If people took all the things they need public toilets for (peeing, pooping, hand-washing, changing babies, emptying colostomy bags etc) and did those things on the street in front of tourists, then you would get (among other things) more public toilets.
The only alternative would be to get involved in local government, but no one wants that.
