It's foolishly presumptuous to assume the world will transition to a gold based economy after a collapse. What's more likely is a switch to a barter system. People will be more concern with acquiring basic goods not collecting worthless gold.
Maslow's hierarchy.
Only those in need of basic goods/necessities will be concerned with the acquisition of basic goods/necessities.
Those operating on a different level will be focussing on that different level.
Gold is the money of Kings & Queens,
Silver is the money of Aristocracy
Barter is the money of peasants
Debt is the money of slaves.
Your country... founded on & firmly rooted in slavery will soon find itself enslaved to the rest of the world.
So... you keep cheering as Bernanke & the Fed enslave the American public... printing up debt for your children and grandchildren to come.
