I have a new piece out in the National Interest, explaining why gold, unlike Bitcoins, will remain valuable for many years to come. In essence, gold has an intrinsic value derived from its industrial and decorative uses, and this value is enhanced by the demand for gold as a store of value, and by the belief (mistaken in my opinion, and certainly not an option I would favor) that gold-backed currencies may be restored.
By contrast, in my view, this piece by Robert Murphy misses the crucial distinction. Monetary demand can enhance intrinsic value, but it can’t make an intrinsically worthless asset valuable. He also fails to state the crucial point about fiat money. The “fiat” comes from the fact that a state can demand taxes can declare (“fiat”) that its money is acceptable in payment of those obligations. Hence, as long as the state can enforce its demands, its money has real value.
