Terminology issues aren’t fundamental.
Maybe at the time Hazlitt was writing, trying to keep the original definition of “inflation” made sense. Now maybe it’s too late and the language has already changed. But I don’t know the history of the word well.
You did fine. Most debates are unproductive messes, and most people are hard to work with in my experience. So this went better.
I think trying to bring up banks and guess my position at the beginning was a mistake in terms of the organization or structure of the conversation. But I chose not to get drawn in to responding to that, and you didn’t persist, so it wasn’t a big deal. That was a point where, if you were talking with someone else, the conversation might have gotten messy.
Were the stakes high? Is there some sort of bad outcome you were concerned about?
