Stockman may be going that way, but then he appeared to have always been a zealot from the Wikipedia piece. I've reads some praise of him, because the GOP of that era, despite laying the groundwork for destruction of the New Deal entirely, were not all as socially conservative as the current crop is. That grew under the aegis of Reagan with the televangelists, and it's gone around the bend. Stockman may be attempting to go the route of Paul Craig Roberts, who was called the 'father of Reaganomics' and still says that he supports the overall plan.
Roberts is revered and seen as an intellectual light. He is the darling of the Tea Party, Ron Paul, Alex Jones, Patriot crowd. They all talk about the wisdom of 'Austrian economics,' gold, silver and stocking up for the collapse of society. In fact, they are banking on it and cleaning up shilling for the same system pushed by the Koch brothers.
We see some of these gurus and ideas paraded here from time to time along with rails against the banksters, the Federal Reserve and other stuff that is usually hidden quickly, because it's TOS territory. Same sources. Even Romney, Ryan, Gingrich and Sanctorum went out of their way to appeal to the CTers.
These guys say things that are common sense, although bound with fear. Paul Craig Roberts is much like the surprising subject of the Tim Wise piece called 'Of Broken Clocks, Presidential Candidates, and the Confusion of Certain White Liberals.'
I think Stockman wants in on a piece of this. AFAIK, Preppers and Gun Freedom Fanatics are not in economic straits. Their passions require a good deal of cash or credit. They vote and contribute to a lot of media.
I hope that answers what you asked but logically, no, it's not crazy to try to hold onto things. We have those on the left who are no different in their fears of global collapse - just different cause offered for the their most treasured TEOTWAWKI. I've heard this for twenty years. The real TEOTWAWKI is Obama, and the right knows it. The end of their world as they knew it has happened, but it's not the end for everyone. It never is, even though sometimes in our disgust, we might wish that!
