Why is it worse to water fields than to water lawns, fill swimming pools and flush toilets? Ranches in the West usually must supplement grazing with
hay, which is grown in irrigated fields which take a lot of water -- but, so what? People need to eat and food is grown on farms and it takes a lot of water to grow food.
If we replace farms with suburbs on the existing arable land and use water for municipal use rather than food production, it will get expensive, but we will probably be ok until our food suppliers decide they can't spare any. An oil shortage we can survive, but a food shortage will get very ugly.
Other than frustration and envy, I don't see what the problem is. Now, in most Western states, you are allowed to harvest rainwater that falls on your property and have a storage capacity of around 2500 gallons, some more, some less. In most states, if you do not have access to municipal water, you are allowed to drill a well for household use (many rural counties require it in order to get a habitation permit -- if you can't find water, you can't get a permit). If you need water for agricultural use then you must be prepared to pay for it, just like everybody else. If there is no water or water rights available for sale, or you can't afford it -- that can be a real bummer. When you buy property, try to make sure it comes with
enough water rights for what you intend to do with it, or make sure you can secure those rights within your budget.
You are allowed to maximize use of water that falls on your property, you just can't impound it. There are a lot of runoff agriculture methods, Holzer's included, that are very effective.
Some states forbid
reuse of water, as a water right is considered to be for a single use, then it must pass on to the next user. These laws are being reconsidered, especially in urban areas that are looking to use processed sewer water for use in secondary water systems. It is more feasible in closed basins, where the treated effluent would otherwise not be used, like Las Vegas and Salt Lake.
I understand that it is constraining and seems unfair, but it is how society works. It avoids anarchy.
I looked into all this 30 years ago when I dreamed of putting together a little desert homestead. It wasn't going to work out so I went on to other things. There are a lot more options, technologically, now, and if I were in better health I might even consider trying again.
After all is said and done, if you just can't abide the West's byzantine water laws, move to where it rains more.
