I know for a fact (and this goes back 25+ years) that outfitters were leasing up deeded property JUST because it accessed exclusive access to public land—absolutely nothing to do with the actual deeded land.
We had one outfitter (after folks started learning about a big block of BLM land that was accessible by a corner of BLM) that convinced the county commissioners to close a county road that accessed that corner
The upside of that story was that BLM eventually punched in their own road into that block
