The federal government then changed the rules on him, and gave very flimsy reasons for doing so.

The federal government had no right to make those rules. See #22.

Your reasoning is incredibly shaky.

That land is valuable.

The federal government has the full authority to extract value from that land for the benefit of the public treasury.

Charging grazing fees has a long and established legal history.

Why should one citizen get to benefit from the land without paying? If Cliven Bundy has some mythical "right" to profitably use federal land, why can't any individual citizen just move there, build a house or a factory or an amusement park on it?

It's federal land, and the federal government has authority to determine its use.
