All the conspiracy theories aside there are a couple of deeply-held beliefs that approach legal status that drive this whole thing.

The Bundy's, and others, claim a property right to graze on public land. The Feds say the law says different. BUT, banks loan monet based on the value of those grazing rights and access rights. In essence, you show that the profitability of your business (from which you are seeking a loan) is based on the leases and access to that land at a certain loading rate. My credits is based on that access and taking it away, for whatever reason, can lead to bankrupting me.

I think that the Federal Gubmint has some serious work to do on these issues. As bank and loan regulators, they have at least tacitly approved the concepts. Simply cutting it off now is probably a bad idea.

This is not to say that threatening to shoot people is an acceptable answer, but I think both sides have blame and neither side seems willing to find an answer that is not 100% of their current position.
