Once the dollar/fiat currency becomes fully devalued and nobody has confidence in it anymore you will not be able to use the worthless dollars/digits/currency to purchase the things you want and need (like food, water, shelter, gas, entertainment, etc...). On Top of that it will have no other value or use (except maybe to start a fire if you have paper dollars and not digital). With gold and silver there are many other uses for them (electronics, jewelery, solar panels, electric vehicles, etc...). You can easily take the metal to a dealer, pawn shop, metal refiners, metal scrappers, etc... https://www.youtube.com/watch?v=sF27Bud0Gh8&feature=youtu.be https://www.youtube.com/watch?v=Z0sbkQLqgjM&t=6s
