If we had a perfect theoretical world where we had complete stability, then you could have inflation running at 0%. But in the practical world that exists today, you can't target 0% because of the damage that you could create by creating deflation. That was why I was saying that from a point of view of lowering the target to 1%, you start to run the risk that because of the way we measure inflation and some of the imperfections of the measurement, you actually could be creating a deflationary style of environment.
On your other observation, I actually don't think economics is rocket science. I actually think most of this is pretty simple.
