The anodizing is providing some protection,. but it can still get scratches, gouges, and whatnot. This finish is an aesthetic preference. Once you get it to this mirror-like finish it will eventually oxidize and dull over time, but you can just use aluminum polish to bring back the mirror-like finish. And if it gets really dull and/or scratched, you can just use the cutting compound and polishing wheel (or even sand it again if you need to take out a deep scratch) as often as desired.
How does polishing it protect it from damage? You've already removed the anodising which protected it in the first place.

CHAIN RINGS ARE NOT POLISHABLE?
Maybe it is but i think its harder material , for me its doesnt make sense and a risk of teeth 🦷 destroyed
