My question seeks to understand the logic behind urban irrigation policies recently proposed in California. Inherent in this question is the fact that certain aspects of the policies don't seem to make sense. So my question by necessity must point out these apparent problems. And when people come back and repeat illogical things (like say, replacing a lawn with something of similar economic value but less water intensive is as easy as buying rice from another state) I have to help them. So it seems impossible to ask the question without somewhat discrediting the policy under question.
Furthermore, the notion that I'm "not trying in good faith to learn" is preposterous. I cultivated a healthy, civil discussion, and learned 3 main points from the discussion comments, which I posted at the bottom of the question (since answers are not possible once the question is closed).
Should the question be closed for "discrediting a specific political cause", given that some amount of discreditation seems unavoidable?
Update
The question now addresses basic water thus:
The value of this water for human consumption is much higher than that, it's a tiny fraction of the water supply by volume, and the state essentially buys basic water (including washing water too) for everyone for free anyway.
And then, regarding lost revenues if lawns are banned:
Ironically, these lost revenues would actually make basic water more expensive. In much the same way as flying Economy would be much more expensive if First Class were banned.
I'm not sure what all the fuss is though. I already addressed Basic water extensively in the comments. My concerns about the policy don't really depend on what fraction of water is considered "basic". It's less than the overall 10% bucket for indoor urban usage. My point is that there's lots of current Non-Basic usage, and it's mostly less valuable than lawns. And the policy seems to serve to make it even more so.
