Yeah, we have a common government that sometimes builds things, which is maybe more efficient than farmers shooting at each other over who diverted the river. Water rights are considered property, and you can't just go take them without recompense. But really, what are you after? California is going to use the collected water it has allocated for agriculture for that purpose, and the only thing you're going to accomplish by increasing what farmers pay for water is change the water usage patterns, so you'll replace a lot of alfalfa and rice with more almonds, pistachios, and wine grapes. Is that good or bad? I don't know.
