Of course other precious metals would follow suit.
EVERYTHING would follow suit.
Amazing how many people don’t realize that money represents relative wealth. A good suit or handgun always is worth about 1 oz of gold; all three will be (roughly) what we currently call $1000. Three gallons of gas will always be about 1 hour of mundane (minimum wage) labor; both will be somewhere around what is currently $8. Sure, the exact numbers & ratios may vary, but they’ll stay roughly the same. Increase minimum wage by fiat, and after an adjustment period you’ll find four loaves of bread cost about the same as sweeping floors for an hour. Declare an ounce of gold is $8000, and the price of a good suit or semi-custom handgun will jump to about $8000. There will be a brief period of chaos (during which some people will become extremely rich, while others lose everything), but it will all equalize out.
Declare the dollar to be worth whatever you like; prices will adjust to reflect it. Hyperinflation, and subsequent monetary collapse, happens when there simply isn’t enough value in society to pay off the debts - no matter how you redefine the fiat currency’s value.
I enjoyed a nice laugh at this. Learn some economics.
