To explain this in a way that people on this forum will understand: A currency relies on network effects. The dollar is kind of like twitter. It doesn't matter how much it fucks up, network effects ensure it's continuing dominance.
Actually the dominance of a currency is harder to challenge, since you can post the same text on both twitter and mastodon, but you can't invest the same money in both dollars and euros.
