You use the most idiotic interpretation you can imagine and then stating it as a fact. I'm sure that you are not doing this in bad faith, but your thinking is missing basic common sense that cripples you ability to understand society. Human right to water and sanitation (HRWS) is very reasonable right. It means that HRWS rules over other concerns in legal disputes and affects policy priorities.
This paper has real world legal cases and interpretations: https://www.un.org/waterforlifedecade/pdf/human_right_to_wat...
They should move somewhere where they can get water. UN may pay for it or whatever. But to show people in some rotten place and complain that they don't get their human right to water makes no sense.
Also, the point of finding "most idiotic interpretations" is to make it obvious if something makes no sense. You are just not used to logical thinking (here, finding trivial counter examples).
I only know about Nestle, there often is the story about them supposedly depleting water in dry regions (I think Afghanistan or Pakistan). But if you look it up, they take the water from a very water rich region in that country.
Next time you read that Nestle story, look it up. I don't have time to Google right now.
