Yes I disagree. What do you expect from someone named Discordia?
What about monetary systems based on the gold standard which have provided stable prices for decades and centuries (punctuated by outburst of price inflation during wartime episodes mostly)? What about a system based on Bitcoin? I dare say most monetary systems are not inflationary...it's just that currently the fiat monetary system (which is inflationary) is ubiquitous.
Oh there might be some confusion about inflation. It helps when we clarify whether we're talking about monetary inflation (which is easy to pinpoint by definition) or price inflation (which is harder to distinguish and even harder to describe how it works).
Since I find monetary inflation to be a much more useful concept than price inflation, that's what I'm looking at. And what I see is that Quantitative Easing = adding to the money supply = monetary inflation. Feel free to disagree.
