"When someone pays me, I receive the purchasing power of that money at that time, why shouldn’t I be entitled to that purchasing power in perpetuity? Well, because purchasing power is temporal; if a bubble bursts, or the economy dives, there is no reason at all why I should be able to buy the same basket of goods as I could at the top of the bubble."
Of course. That's not the point. The point is that there is a central authority that can manipulate the value of money and in so doing can favor of disfavor different players in the economy. It's also quite un-democratic. There are criticism of this from the left as well as the right. (For the life of me I've never been able to figure out why some on the left consider the existing Federal Reserve system progressive.)
The author also conflates libertarianism and conservatism, which isn't something you can just do with a hand-wave. The former is far more complex than that. He also tosses out red herrings about the 9/11 "truth" movement and similar things to achieve guilt by association.
Crummy article.
