I can't imagine learning German or some similar language and complaining that their words aren't clear just because I don't speak German fluently enough.

The point OP is making that those words are intuitive for readers (everyone). Knowing language is one thing, but intuitively making sense of similar words in a new context is another. Most non native English speakers think in their own language. Seeing word “authorization” simply doesn’t evoke the link with “authority” in their own language.
