I think you'd want a justification for subsidizing selected farmers and foreign countries imports other than, it makes the largest landowners the highest short term profit. None of it will exist long term unless global warming increases rainfall in the western US. How to rectify? The simplest is to charge/tax farming with scarce water for export. The next is to allow metro purchase of water rights (already happening).
