There's a difference between people freely choosing what assets are acceptable to back a given currency and having many currencies floating in value against each other, or the government deciding what each currency can be backed against and at what value (the National Banks had to accept each other's currency at par value).

Yes, of course. But if you have currencies backed by too many different kinds of assets those currencies aren't money any more, they are tokens in a barter economy.
