The economy doesn't lie, even when the government does things like declare legal tender. Declaring something to be legal tender, even fiat currencies, gives them economic value until it doesn't anymore.
This was actually a problem with silver in the late 19th century (hence why we are on a gold standard and not bimetallism).
It also requires faith that a government with significant gold reserves won't sell them all off.
Certainly, in our modern world, nothing is terribly certain and I wouldn't argue for gold an answer for those seeking a haven to store their value in.
