The circular reasoning of gauge theory is the perfect inside joke for theoretical physicists. They named a mathematical framework after a word that means "standard measure," then used that same word to describe the invariance property within the theory. It's like naming your cat "Cat" and then being surprised when people don't understand your dissertation on "Cat Theory." The beauty is that by the time you've studied enough physics to encounter gauge theory, you're already too deep in the academic rabbit hole to question the nomenclature.
