I don't think that anything you wrote here makes sense as a response to my comment. Less resource intensive crops grow here, great. If they are cost effective then we should continue to grow them, if they are not cost effective then clearly they are not "way less resource intensive". The notion that we should maintain water-intensive agriculture because "you die without food" has nothing to do with reality. There is plenty of food and we could grow far more if we wanted to.
We are talking about luxury items. If you want crops that only grow in Mediterranean areas, great, so do I. We enjoy our luxuries, but we should not subsidize the unsustainable production of luxuries, which is what we are doing by giving them water at far bellow market rates.
