Melt a gold coin and you can still sell it for 300 dollars an ounce. Burn a dollar bill and it's worthless. It has intrinsic value because it's basic building block is an element. And that element is used for jewelry, electronics, and space equipment.
But we're giving it a lot of value. Important to understand the difference between intrinsic value and accepted value. Good currency doesn't have intrinsic value, things with intrinsic value are useful and it's bad when people start using your money as something other than money.
No it's good, like I said, because no matter what happens, you can always get value for it.
