I actually like the way you care for your collection. I'm only learning to do that now and I have to enforce that on myself since I don't want the kits I worked hard on to get damaged and since I'm gonna have nephews/nieces in the future: destroyed. I want to take my old projects out of their boxes someday too in good condition.
This is (just) me and I know some people do it differently...
But, I take out a or (rotate) a single figure (once in a while) to let it - 'breathe' - then after awhile, place it back into its storage.
I started doing this, (after) I experienced the water damage done with the 2 collectors editions of the Dirty Pair Manga,so I (now) always check my collections regularly and rotate the stock (so to speak).
This way I am aware of any changes occurring with them and if anything is seen that I am missing.
Simple little things like pressure marks, bends, dents on boxes or the plastic, dog-ears on a Magazine, or (even) simple "storage wear" will start to show, so I feel that by doing that, I am (at least) avoiding it or prolonging it from happening.
I am sure that many will have different ways of attending to their collection personally, so whatever works, is well worth doing imo.
