Because this method of judging inflation by using “equivalent” substitutes completely ignores the change in quality of life. Real inflation is what happens when my behavior doesn’t change at all, but my costs increase. If I keep making adjustments to my behaviors then I’m just trying to counteract inflation, it doesn’t mean inflation isn’t happening.
