The argument is not that this is controls the USD value. Instead, the argument is that this gives an intrinsic base value to the USD. This base value means people have some reason to hold USD, which causes them to make other transactions in USD. The actual current value from USD comes from the other transactions, but that is not intrinsic to USD. Instead, it is an emergent property.

The intrinsic value of USD is consoling, because it prevents the value of USD dropping to 0, hence there will always be a possibility of the emergent value reappearing.
