She says returning to an authentic gold standard — in which dollars are redeemable for a certain amount of gold — “would not be feasible” now, because there are too many dollars in circulation relative to the U.S. government’s store of gold. Such a standard hasn’t fully existed in the U.S. since the Great Depression.

But, she added, “it might be worth trying to incorporate some aspect of a gold/silver link to a future debt instrument to add intrinsic value.”
