They printed away our futures

If the amount of potatoes we produce every year goes up and the amount of currency we print every year goes up but the amount of gold we have in our vault stays fixed, the real economy doesn't care. You're trading dollars for potatoes and potatoes for dollars. The gold is irrelevant.

But if potatoes go up and currency stays fixed, you have too few dollars chasing too many goods. This deflates the cost of the potato and discourages the next crop. Smaller crops mean food shortages. And food shortages impact social stability. So now you've got riots from a food shortage that was created entirely because you didn't print enough currency to buy up all the potatoes.

The problem with this argument is that it neglects the consequence of specie entering and existing the market.

The California and Alaska Gold Rushes did more to devalue the money supply than anything Nixon tried. The Spanish economy of the 1700s imploded in the face of the gold glut it imported from the Incas and Aztecs.

A gold standard doesn't stabilize the money supply. It simply deflects the question of what that money supply should be onto the private commodity market for gold. But volatility in the gold supply does happen, particularly during times of economic turmoil. And a pegged currency encourages private arbitrage, which increases the frequency of these sharp shifts in gold availability.

And that's not even getting into what happens when you've got a private speculative asset independent of gold - maybe we call it real estate or company stock or cryptocurrency - that siphons off investment dollars one minute and floods the market with currency/commodity-hungry panic sellers the next. Even if you've got a stable gold/currency ratio, these aren't the only two variables in your economic model.

No amount of gold changes the number of potatoes the Irish have to eat.

Holding cash makes it sound like it only impacts those who have cash savings, but it takes value away from the work you do as you get paid in cash and those wages never keep up to inflation from the printing machine. So they "invigorate" the economy by devaluing your work.

Nations and empires have used the gold standard for thousands of years.

Crack open David Graeber's "Debt: The First 5000 Years". He's an anthropologist who spent his career investigating this theory, and he found it wanting. Hardly the first, but probably a more fun read than Thomas Piketty or Milton Friedman or Adam Smith. Nations and empires didn't use gold specie until fairly recently in human history. Most of human civilization revolved around different types of credit and debt, typically enumerated in volume of agricultural produce.

Wheat/corn/rice, fish, olive oil, and salt were the most common standards of exchange. Gold was ornamental, but far too little of it existed to circulate as common currency or even reserve currency. It wasn't until the colonial era and the mass exploitation of Africa, East Asia, and the Americas that European Banks had a large enough surplus gold reserve to treat it as coinage.

So you're talking at best hundreds of years, and even then only within the handful of European powers capable of plundering the gold reserves of foreign nations on a global scale. And even that only got these countries from the 15th to the 18th century before the system started breaking down.
