You have the problem of states selling/leasing land to foreign enities (of course the feds do that too) and that may be his concern.
The enabling legislation should address that issue completely. But as I read his post, he appears to be one of those people that want to enjoy the “pristine land that no man has entered upon,” so he's just a elitist who doesn't want “his private preserve” opened to others. The fact is that the states with little or no Federal land ownership have manage to “preserve” the naturally beautiful places in their states, so it all hinges on state leadership. Beyond that, with all these federal “set asides,” we have seen areas that have minerals and petroleum that we need going forward. We are well beyond the point where businesses can get away with being land rapists, and again proper legislation at both the state and federal level should safeguard the environment.
