Gold is flat vs oil
But how about vs food?
I've researched this for discussions of fiat inflation, and even good food (eg beef) is cheaper in gold than it used to be
How about vs consumer electronics?
Definitely much cheaper
I think "money supply" is not the appropriate deflator, because a money supply that expands (as Bitcoin & gold are both still doing) more slowly than the population & productivity grow will gain in purchasing power despite "inflation"
But yes, most stocks & bonds will underperform just owning real money
