Where did I state it wasn't a good thing? I stated that unless he targets the real wastage of water especially by the agricultural and tourist/golf/resort industries you are not going to achieve much if at all. You could ban lawn watering and car washing altogether and yet more than 80% of the water would still be wasted on the agricultural industry. So unless the governor is willing to take on the big business and agriculture industries (he isn't), nothing will change. California will still keep using tens of trillions of gallons of water they are rapidly running out of.
It reminds me of the ban of pesticides for home use in BC. A lot of people cheered when weed n feed products were banned in Canada. Until they realized that homeowner use of pesticides is nothing compared to the agricultural and industrial industry. All those studies about pesticide runoff to streams, dead animals etc. They had less to do with Johnny Homeowner sprinkling weed killer on his lawn and more to do with idiotic farmers spraying pesticides by thr thousands of gallons over hundreds of acres, companies using weed killing products in golf courses and resort areas known to animals etc. But nope the ban for commercial use never happened, but now Canadians have to either smuggle weed killer from the US or use concentrated hand spraying products that are costly, time consuming and work a fraction as good.
