Now, the efficacy of the incurred debt is a whole other matter. Sure, you can incur debt that improves GDP and incur debt that doesn't. Presumably the government would do more of the former and less of the latter. But that's why governments need to be monitored and the people need to have levers to hold them accountable. How good the levers are in the US, I'm not entirely sure.
For me this goes a key difference between fiscal and monetary policy. If printing is forced by horrible fiscal policy (like helicopter money or the inflation reduction act) then it's an issue with the fiscal policy. Fiscal policy is the biggest threat in my opinion.
The stock market, at the end of the day, should be a capital allocation tool. That's what has allowed the US to reach as far as it has with wealth generation, productivity, inventiveness etc. I think the monetary policy mistake was to keep the cost of capital so low that companies were able to go public without a viable path to profitability (see peleton, uber, rivian). It also create huge asset bubbles. I think the extreme low cost of capital has also contributed to wealth inequality in a negative way. I certainly don't say that with a socialist bent. I think if the market is properly allocating capital to productive ventures, then society generally benefits. The benefit could be wealth or it could be skills and experience.
As to what the proper debt/gdp limit is, maybe it's a function of the central bank credibility as it pertains to being able to pull the levers timely and effectively and keep investors' confidence.
