Gold is money because it's rare and can't be counterfeited. Now apply that to any modern currency and see if it holds up.

You miss the point when you say gold has no uses. Gold's utility is in its qualities that make it a good form of money. The global digital age reduces that somewhat, hence the discussion of digital gold.

Perhaps you can answer me this: if gold's only value is because it is worth money then why do central banks like the Federal Reserve hold large quantities of it on their balance sheets? They have the ability to create an infinite supply of currency, so by your reasoning they shouldn't value gold.
