I knew I should I have left in that last paragraph I wrote, which was something like this:

I know that inflation is a type of devaluation, but for the purposes of my argument I am differentiating the two in that devaluation is a more bare-assed unabashed gouge vis-a-vis inflation being a slow, gradual, uncontrollable devaluation.

(I left that paragraph out since I thought it went without saying. ah well)
