I think that there are probably tens of thousands of small land-locked parcels of BLM property that could be sold without causing any negative impact to other American Citizens.
For example, my MIL owns a ranch in Colorado that has two land-locked pieces of BLM land within its boundaries. One is a whole section, 640 acres, and the other is approximately 67 acres. She leases the grazing rights for almost nothing, but would be happy to pay fair market value for those 707+/- acres just to be rid of the aggravation of dealing with the leases and to have the opportunity to improve that land. I'm reasonably sure that a majority of ranch owners who are in similar situations would also like to buy their land-locked leases.
