Well there is a difference between land ownership and land use.
For example, mining claims have typically been allowed on public lands. At a time when elements for semiconductors, rare earth magnets and similar that are critical for military and industrial supply chain security, these mining claims have been banned by the feds - even after approval from the states. Other countries, especially adversarial ones with far fewer or even zero environmental safeguards have already developed monopolies both domestically and in third world countries.
Oil and gas leases have also been essentially shut off nationwide, resulting in our dependence on hostile nations for fuel. At the same time our strategic petroleum reserve has been bled down to nothing in order to somewhat stem the inevitable price increases in an effort to buy votes at the expense of our security.
At the same time the Chinese have been fishing illegally wherever they can get away with it, meanwhile bullying small countries out of their own territorial waters with naval vessels.
Forestry management in certain states has also been an unmitigated disaster. Banning selective logging and controlled burns in the name of ecology or something results in vast amounts of undergrowth and dense timber and brush. Then when lightning or powerlines inevitably cause fires, they burn uncontrollably and so hot that they burn down even to the roots. Then when it rains there are rock and mudslides that wipe out roads, houses and etc. leaving a wasteland with no habitat for wildlife. In places like Europe and Japan they have managed the forests for centuries, unlike our modern 'enlightened' eco 'scientists'.
They really believe that humans are an invasive species to be eradicated whilst protecting endangered cockroaches or whatever.
On the other hand the number of cattle allowed to graze on BLM and National Forest lands is obscene, and, coincidentally, profitable. You can't even pitch a tent in most meadows without clearing half a dozen cow pies. The numbers must be reduced substantially IMHO.
