I've read it. Rothbard, and the Austrians in general, are wrong though. The narrative of the Austrians, laid out in Carl Menger's "The Origin of Money," and picked up by Rothbard, is that barter precedes money. That's historically false. Barter, in actuality, historically emerged in economies that had previously used money. Barter follows currency collapses, but money actually precedes barter, historically. Primitive economies, prior to the emergence of money, almost never used barter. There was no market. Instead, their economy was more of an informal "gift" economy, only the gifts weren't free gifts but seen as obligating the receiver to give in turn when called upon. It is sometimes called a "gift economy," but it's really more of an informal credit system.

A good read on that subject is "Debt: The First 5,000 Years" by the anarchist anthologist David Graeber. Although the title is "Debt," its really more of a history of money.
