Absolutely, this is the ideal. All the examples you mentioned are what I would class in my previous comment as non-essential use cases (as in there are alternatives). Certain alternatives such as desalination and water reclamation in industrial processes don't change the elasticity of water economically; it's still required. They just increase the amount available in the pool (excuse the pun) and even then these too bear cost for implementation and maintenance and would not be provided free (which makes sense).
