@newstik By the way, it also seems like the author either doesn't know about the Bretton Woods system, or is choosing to misinform the reader intentionally, since the U.S. Dollar, and thus also the other 44 currencies pegged to it, were convertible to gold at a fixed price, until Nixon unilaterally (and allegedly "temporarily") bailed on that in 1971.
These are not simple mistakes when someone chooses to construct arguments based on them.
