You've linked to a privately written article ("The views authors express in Economic Commentary are theirs and not necessarily those of the Federal Reserve Bank of Cleveland ") by someone who worked for the Cleveland Fed, who blames printing currency for inflation. No doubt that debasement of the currency increases the nominal prices of things. But it's hard to square the idea that that's all there is to inflation when you consider that lots of countries had inflation after COVID. They didn't all coordinate on printing currency.
I've never actually seen anyone use "inflation" to refer to cost of living. Most economists use the term to talk about price increases of a subset of goods, but that isn't directly measuring cost of living.
Most people are not economists. All they know is they're spending more for less every month, and they don't like it.
The money supply idea has always been Austerian crackpot nonsense, intended to dissuade governments from investing in public services of all kinds because that's socialism, and we certainly don't want any of that.
In reality price rises are mostly driven by corporate profiteering, and sometimes - as in the oil crises of the 70s - by supply shocks.
This isn't entirely accurate, either. An increase in the cost of living occurs when real wages fall (in other words, when workers paid less, in real terms (adjusted for inflation), for the same amount of work). In principle, inflation doesn't necessarily lead to an increase in the cost of living, although in practice usually it does.
