It's not about disallowing the other guy from doing stupid things and not being rich anymore, it's about not allowing someone to waste precious resources essential for human life, so as to not make it harder for others in need to have access (at accessible and fair prices) to said resources in the future.

Not unless the cost of water is super, super expensive. Which it won't be.
