That may be 100% true, but the market can remain irrational longer than you can remain solvent, and in this case, gold has been doing awkwardly well under current conditions.
IMO, combining gold money arguments with observations about the price of gold is contradictory. If gold is money, then you should never wonder about the "price of gold" as gold should be used to price things.
By the article's _own_ parable: if you were starving on a desert island, you wouldn't be relieved to be airdropped a briefcase full of gold. You're benchmarking money to money.
