I agree liberation day was a significant factor. But on the exact same day, the Senate passed its Budget Resolution. There were some economists that opined that much of the bond market's issues might be just as much related to that event as tariff liberation. They woke up and said oh crap, they ain't serious about the debt ratio (debt).
Without looking it up, Japan is a good example of a government that let its debt ratio get out of hand. May have led to its lost decade which was really longer then that. And we have the examples of Banana Republics. My point is simply that its a good idea to address the ratio. If anyone is claiming that we can ignore it, then I think the preponderance of historical economic evidence proves that wrong.
As to printing money, I suppose the government does a little of that just to support economic growth when the Federal Reserves buy's Treasury's. But in general, the Fed almost always keeps the money supply in balance to keep inflation in line. Now they did a bunch of that (or quantitative easing) after the Great Recession. But pretty sure, in recent years they have unloaded most of that.
There are certainly more qualified folks on this forum to give better answers.
