I feel like a few folks are playing devils advocate for a fringe group here. Why are we entertaining hypotheticals for something that only folks like Mike Lee perceive as a problem?
Sure, many people back east may not use their federal public lands, but many do. Perhaps not a majority, but those aren't the folks calling for divestment. As was previously mentioned most of them either don't know or don't care about access to public lands, so it's obviously not a problem for them.
We're debating solutions to a problem that doesn't exist.
