He opens by noting,
In some free-market circles fractional reserve banking (FRB) is blamed for everything from business cycles to bad breath. Defenders are seen as apologists for inflation and fraud. Thankfully these views remain a minority because they are gravely mistaken. As I, and other Austrian monetary theorists, such as George Selgin and Larry White, have argued, there’s nothing wrong with FRB that getting rid of a central bank can’t cure. Fractional reserve banking works just fine in a free market.And here, in a few words, is the point. The problem isn't with FRB as such, it is more to do with having a central bank. Get rid of the central bank and move to free banking and FRB would work just fine.
