Yeah big agree. Gold was also easy since it was a lingua franca commodity, instead of maybe a modern version being a basket of commodities backing a currency.
I understand the implicit reason they dumped the gold standard. Your industrialized economy can grow a lot faster than you can mine new gold out of the ground. Deflationary pressure meant there was pressure to print more paper dollars than there were gold backing them to stave off inflation. France calling the US' bluff on gold backing by repatriating their reserves certainly didn't help at all.
The big benefit though is like you said. You can't fuck with gold the same way as fiat. You can't magically make more, much like the current Iran conflict is going to crash the world economy because a bunch of idiots in the US think they can print oil...
Knowing you can't print gold is supposed to be a stabilizing influence on a country's fiscal policy. Don't fuck with your own currency lest you ruin it, cause a bank run, and debase it to being worthless and need to start over or borrow a foreign currency's stability.
A basket of commodities could be the way forward though... That's basically what the Petro-dollar is informally. But if you made some kind of international trade currency that was basically a warehouse receipt for X amount of gold, silver, wheat, barley, oil, sulfur, ammonia .et, that basically all countries use, maybe that would work?
Digital currencies like Bitcoin or other speculative assets just don't work long term...
