The problem, while your data is probably accurate enough conceptually, is that DCs showed up too late to the scene - the water isn't accounted for.

DCs, new golf, new homes, new alfalfa, new ranching - the math isn't there.

Tech people saying ignore the water problems are saying implicitly that AI, despite showing up late in line for access to a resource that's an old, old problem in the western US, is more important than hearth and home considerations fighting for the same dwindling resource.

The average western farmer/rancher, their own judgement and contributions to this problem aside, definitely love coastal tech people sniping their pre-colorado compact water rights via all that goes into getting water rights like that.
