ELI5: Why can't/shouldn't we go back to the gold standard?
gpt
Gold is a luxury item.  Only 10% of gold is used for manufacturing or technical purposes, the rest is used in vanity goods like jewelry or hoarded as an investment.  Therefor, its value is perceived rather than practical, and as such the price is subject to whims.  (See: gold rising to insane levels as people fear an economic meltdown.)  By basing your currency on the stability of your government rather than a finite resource, you open up a lot more flexibility in terms of  monetary policy.  Also, since governments generally move slow and avoid drastic measures, the value of the currency remains relatively stable over long periods of time, which commodities like gold and oil do not.

Short version: Businesses like it when the value of a dollar is stable.  It's a lot harder to maintain stability if your currency is tied to a finite resource.
