I fully agree.

Interestingly they have similar dynamics: due to the scarcity of that public resource, the cost of providing it becomes very high, which causes it to become more scarce. In the US, a business providing a public washroom has to deal with very heavy usage, because of how rare they are, which makes maintenance expensive. They become the bathroom for the whole neighborhood. In Japan, businesses can offer clean high quality washrooms at little cost because there are many others sharing the load. But a convenience store offering a garbage bin in a popular area will quickly find it overloaded.

This creates a feedback loop where scarcity drives further scarcity.
