The “famous” cases of hyperinflation—Weimar Germany, Argentina, etc—all come with extraordinary political instability as well. I’m not an economist, but it seems to me safe to say that hyperinflation is as much a political phenomenon as it is a monetary one.
Now, it’s certainly possible that the US is facing such political risks, what with efforts to disenfranchise large groups of people, entrenched rule-by-minority, and one of the two major parties expressing strong support for anti-democratic ideologies. (See https://carnegieendowment.org/publications/86352, for example.)
But when people express concerns about hyperinflation—without mentioning the political component—it’s a bit like having a suspicious growth on your shoulder, and worrying that the diagnosis might come back that you’re not going to be able to walk around shirtless anymore.
