There is nothing that says the printing of money in 2008 had to lead to immediate inflationWhich is exactly what Keynesians were saying. The Monetarists said otherwise. Guess who was right?

Those "things" which have risen in price does not count as inflation. It has never counted as inflation. There is a different word that should be used for that phenomenon:

I do not understand why this is difficult to understand: inflation/CPI is the cost of goods and services that are used on a daily/weekly/monthly basis. Asset prices are not one of those things.
Please stop using "inflation" when it comes to asset prices, as it does not apply. It's like pointing to a Boeing 787 and saying "boat".
> In economics you’re right until suddenly you’re not.
In economics, at least "good" economics, there are models. These models describe reality: some models are better than others. We should follow the ones that make (more) accurate predictions.
Keynesian models (for example) had problems with stagflation in the early 1970s, but by 1978 most text books had explanation as to why the earlier models broke down, and why the phenomenon occurred in the first place:
* https://en.wikipedia.org/wiki/Stagflation#Neo-Keynesianism
Some folks' models said inflation would occur from money printing post-2008; others' models said it was not. One group was right, and the other was wrong.
Similarly: a bunch of folks are worried about inflation after the US Congress passed the $1.9T rescue plan, others are not. This is an(other) experiment in which some folks will be right, and others wrong.
Whose model best/better describes (economic) reality?
AFAICT, the Keynesians have been right more than any other school of though. I'm sure they may/will be wrong at some point, but hopefully something will be learned and models improved.
