I'm not sure this is true - the base case seems to be the Eurozone, the countries of which intervened in their economies enough to forestall a depression, but not to the extent that the US did. Eurozone inflation is just a notch above 5%, unemployment rate right about 7%. In the US it's 7% and 4% respectively. In effect, the US traded a ~2% rise in yearly inflation for a ~3% reduction in unemployment. Reasonable people can disagree on whether that was a good trade, but to say that we could have just "skipped" all the COVID disruptions and maintained low inflation, low unemployment and typical GDP growth strikes me as fantasy land. There wasn't any magical economic policy prescription that would make everything "normal".
