There's probably an argument to be made for a new standard that is based on a unit of energy or something, something that has true intrinsic value.

But gold has worked for thousands of years as a stable currency. Whoever wants it replaced with something else, or even nothing else, has the burden of explaining how the new system is better for the people using it.
