No they’re not interchangeable. They are all designed with each other in mind, along the spectrum, to maximize profits under constraints, and the reality of rivalrousness is one reason to not simply try to run at 100% capacity every instant.
I can’t tell what this paragraph is responding to. What are “they”?
You explained they popped up from the ground. Those are just about the most excludable toilets in existence!
Okay I do feel a bit silly for missing this… but I also still maintain that “allows everyone or no one to use” is a stretch when it comes to excludability. (Like, if the reason we’re talking about it is “can the free market provide this service at a profit”, then we care about “can the provider limit access to people who are paying for it”. If they can’t do that, do we care that they can turn the service off during the day and on at night?)
Overall it still seems like you want to use words in a way that I think is unhelpful.
