The definition of monetary inflation is increasing the monetary supply. That doesn’t need to happen by starting a printing press. It could be someone typing a bunch of zeros on a keyboard somewhere to create new money out of nothing.
I never said inflation was detrimental or harmful (my personal belief is that it is harmful, however), just that adding money to the supply is by definition monetary inflation (the origin of the concept of cost inflation which is what we’re being asked to accept as the true definition). Putting air into a balloon doesn’t mean it will pop; it’s still being inflated. Hey, it’s even more fun for a while ;-)
I was responding to a parent who said printing money isn’t inflation, when it’s the literal definition of, and the origin of the term in monetary theory. It’s not very constructive to conversation to attempt to change meaning of words to make one point or another.
