Which is the point Libertarians are trying to make! Taxation is theft according to libertarians. Inflation, like taxation, is theft. You actually ended up agreeing with them by saying that inflation is no worse than taxation. To libertarians, tax and inflation are both theft.
Instead of telling libertarians "Why inflation is not theft ", you ended up echoing the libertarian sentiment that inflation is no worse than taxation.
It simply argues that both statements should be treated with contempt, especially since the former has recently been in vogue.
So yes, if you ignore half of reality, you are right!
and what is this? "If the state endows the money with value". Money have a certain value because everybody using them agrees on that value. Dictatorships tried and failed to "endow the money with value". What happened in my country was that some alternative, valuable papers were created. Like a card for bread ratio. That piece of paper had value even if nobody was calling it "money". Or other papers that gave you some rights like buying a car, getting an apartment, vacation tickets etc.
"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.
And the propensity for libertarians to indulge in conspiracy theories is more than guilt by association.
In contrast, government banks are "accountable" only to the whims of politicians and a public that wants its cake ("reasonable" taxes) and to eat it too (immoral entitlement programs). That's one purpose that statist banking serves: to make up for the inherent, recurring government budget shortfall by printing boatloads of money, forcibly lowering the standard of living of anyone that saves, in order to "benefit" those that won't or can't.
As far as conspiracy theories go, it depends on who you're talking about. It also depends on the conspiracy theory. Conspiracies do exist; the phrase "conspiracy theory" has of late been used as an effective tool to dismiss what used to be called investigative journalism or social criticism. Anyone advancing a criticism of the social order or putting forward the outrageous idea that powerful people might organize to maintain their power is a "conspiracy theorist." Obviously powerful people are rational, egoless, dispassionate technocrats and are only concerned with the public interest. All praise the great steersmen!
