Looks like you've drunk the Kool Aid, and have probably paid for enough Mises Institute seminars that there's no point in arguing with you. But I do have to wonder about your choice of words. Rockwell's never seen a secessionist movement that he didn't like or a US foreign war that he did. How does a man who'd just as soon see the country dismembered and who has no objections to its being done violently qualify as a "national treasure"? How does a man who finds more to be said for our killing each other than for our defeating foreign enemies become an "American hero"?
I'm no fan of some of our foreign policies and wars, and I'm no expert on economics, but Rockwell is contemptable because of his "you can have it all" ideology. You can flirt with anarchy, yet pose as defenders of traditional values. You can deny the legitimacy of our government and advocate the break-up of our union, and nominate your leader as "a national treasure and an American hero." Government does indeed have consequences, so does having an army. Not all of these consequences are pleasant, and perhaps some can be avoided. But anarchy and "minarchy" and not having an army have consequences too, which may be equally bad or even worse, and Rockwell ignores such consequences. Sorry, but I'll pass on Dr. Rockwell's patent medicine feel-good cure-all.
