The US doesn't hold "reserves", it takes in taxes and spends them on things. In fact, it takes in about $.80 for every dollar it spends iirc.
Here's the Federal Reserve balance sheet:
https://www.federalreserve.gov/releases/h41/20241003/. To me, that reads "we have $7 trillion worth of assets and liabilities in reserves".
I agree with you that this "institution" ideally shouldn't exist at all (if that's what you're arguing), but in reality, dismantling it is currently impossible. The people who control the vast majority of the world's assets also control this board, and they aren't going anywhere. Right now, there are billions of dollars' worth of assets just sitting idle, contributing neither to healthcare, the military, nor retirement funds.
I don't support taking on additional debt. I'm simply suggesting that instead of allowing $11 billion in gold to sit untouched, gathering dust and losing value, we should convert it into Bitcoin, leave it untouched for 20 years, and then use it to fund retirement, healthcare, or similar needs. Of course, I'd also be open to giving people the gold now and letting them decide what to do with it-- that might even be the better approach, but it wasn't proposed by the people who will be the next government.
