We will print until printing reduces the dollar to ashes. All fiats pegged to the dollar will be ashes well before the dollar, but it's all headed to the same ash heap. That's what fiats do and there is a long historical record to support this phenomenon. Human behavior really hasn't changed all that much.
Sims uses a floor and ceiling analogy; ceiling representing credibility of the fiat. Credibility in fiats fails when the public begins to disagree on value. Primarily, where would we see this public disagreement in the value of the dollar take place; the grocery store, insurance, fuel, wages, every day living costs. The sentiment is usually, "I can't seem to make my dollar stretch as far. People begin cutting non-essentials, making substitutions, looking for clearance sales and bargains. When those measures fail, desperation sets in.
The focus usually shifts to political leadership for answers; often the very people who created the problems leading to a declining fiat. Politicians will offer a number of solutions; all usually worse than the problem. In the last few years, CBDC's, tokenization, BTC, stable coins, etc...are all "perceived" solutions to a failing fiat. Really, those are just the next iteration of fiat to fail, providing a new misery for the people.
Credibility is going to have to be re-established in our fiat. We'll need to back our money with "something" to give it credibility again. There is a long list of commodities, which nearly every country will use to back their fiats. Whatever that commodity happens to be, will provide a floor for access to markets.
That's how I see things.
