The fair way to settle this thing would be for the Bureau of Land Management (heh!) to sell this 600,000-acre parcel (along with all the other land it mismanages) to the highest bidder.
The new owners would be free to in any way they choose. Most likely, they would allow ranchers to graze their cattle on at least a part of their land, at whatever price they agree on. But if they want to build factories on it, or prospect for gold, or build a city, or set up a sanctuary for some stupid desert tortoise (which, amazingly, managed to survive along with the cattle for the last 120 years), that would be their right.
If Mr. Bundy and the other ranchers want to assure themselves of the right to graze their cattle on the land, the simple solution would be for them to submit the highest bid.
