Howdy from Wyoming A.
Here is my place...

There are several small parcels for sale next door to me. 7 to almost 10 acres. Asking around 40,000.00 but you could get them for less.
As in all things the answer to your questions is... it depends.
Some counties have no real rules or codes, some have tons.
There is a lot of cheap land/ large parcels, but they are mostly in the sagebrush. I have seen some with water on them but not many. Most of the time as you get closer to mountains, closer to a town , the prices go up.
Wind is not a problem. In fact there are all sorts of big wind farms all ready in operation and more planned. Many folks have windmills. One of my neigbors has a really nice solar set up too.
Most of Wyoming still has a large farm and ranch community, with the stockmen , especially, hold political clout. If you are outside of most towns there is generally no problem with livestock. As in most places it is about being a good neighbor and having like minded neighbors.
My soil is awesome. Many soils have salts. So be sure to check that out. I have lived in several parts of Wyoming and the soils are all over the map. Most of the time I have found that with water and added organics, you can have very good gardens. I think with the right use of permie principles most of Wyoming could be turned into a paridise.
SHHHHHH. Don't tell anybody ... Most of the time I tell people it is a hell hole, 60 below in winter 90 above in summer. Always windy , always dry. Please stay out...
