But you're afraid to test it now. Have you ever tried to use gold for essential purchases anytime in your entire life?
If I walked up to a farmer and tried to buy a binfull of his wheat for a gold coin right now, he would think I was nuts. He won't think I am nuts if a disaster strikes and the dollar hyperinflates, and he will want my gold coin more than he will want that particular binfull of wheat because chances are he will have no money.
You don't call the fire department when there is no fire.
