Hopefully they are correct that this is the peak.
One error libertarians repeat from conservatives is the belief that all price rises are by definition inflation. They are not. If supply had dropped but demand has not then prices will rise. Usually this is for one or two goods, but in a pandemic it can be for most goods. If the latter happens it looks like inflation, it is often called inflation, but it's really the market signalling consumers to lower demand until producers can increase supply.
Inflation is up nearly everywhere. Much like gas and energy price hot takes, people have the most US-centric inflation hot takes imaginable.
Inflation is up in places that had very limited pandemic spending as well. The inflation story is much more complicated than just "the US spent a lot". And the fix will be more complicated than that.
Inflation also tends to be a bit self-fulfilling the longer it persists, regardless of underlying factors. So hopefully we see it start to get under control in the coming months.
What drives me nuts are the fringe libertarians who define inflation as purely the expansion of the money supply, regardless of price levels. (Expanding the money supply with flat or decreasing prices is inflation!) Makes it all but impossible to even have a conversation.
