I remember reading an article by Rothbard where at the end he stated that deregulating banking isn't helpful when you have fractional reserve banking and a central bank that manipulates the money supply. I think it was answering why conservatives asked why Austrians didn't necessarily favor deregulating banking per se.
Does anyone know what I'm referring to and where I can find it?
Perhaps you mean Chapter 80 of Making Economic Sense, where he writes:
Many free-market advocates wonder: why is it that I am a champion of free markets, privatization, and deregulation everywhere else, but not in the banking system? The answer should now be clear: Banking is not a legitimate industry, providing legitimate service, so long as it continues to be a system of fractional-reserve banking: that is, the fraudulent making of contracts that it is impossible to honor.
