It’s also stupid that many areas literally prohibit collecting rainwater.
I’m inclined toward encouraging all homes to have rooftop solar + rainwater collection, making them at least viable in times of scarcity (blackouts, droughts, etc). Nothing is taken for granted like electricity + running water, and nothing stops society faster than either of those getting turned off.
One of the reasons I left Washington State for rural KY was the rainwater thing. It was the principle. I felt like I lived in the old USSR in many ways. That was one of them.
