Food and water are already largely covered as a basic need in modern countries. Electricity and pubic transport have nothing directly humiliating or existential about them, but people are also negotiating to introduce a basic right for these commodities. Payed toilets in some sense do occupy a special spot in this space because they are such a basic and often very immediate and unpredictable need. This is different from e.g. the need for water, because you can typically suppress it for several hours or even days in an emergency situation.
