I understand the concept. For some (maybe most) of us it takes a while (and many knives through our hands) to figure out what we do and don't like, and what type of knives, blade shapes, steels, designs, ergonomics, and aesthetics are a good fit.
Eventually you may end up with a handful of knives that are right for you, and a number of knives on the shelf that are your "college textbooks" - great when you were learning but you never go back to them.
You are hoping to minimize the loss on resale of your "textbook" knives.
Carrying the analogy a bit further - just like textbooks, if it's in pristine resale condition, you probably didn't read and study enough to get the value out of the class. Same with the knife. If you didn't carry and use it enough to figure out what does and doesn't work for you, then other than just satisfying a need for variety, you didn't get much out of the knife.
There is the other issue, that in today's on-line world, you really can't easily go to a knife store that has everything you want, sit there for a few hours trying out all of the display models, until you find one you like. We now have to buy, try, and resell (usually at a loss). Same concept - you want to be able to resell at a small loss.
All of the above is a restatement / refinement of your original point. I understand your motivation, and it is not unreasonable.
Knives that would quickly show wear from normal use are less easy to resell than knives that show little to no wear from normal use. So your concern is that you want to avoid knives that look "used" really quickly.
So yes - I would avoid knives that have coatings / etches / designs on the blade that would be abraded, scratched, removed, or otherwise damaged during normal usage, if you think that would reduce the sale value of your honestly advertised and represented "carried, used, sharpened, but still looks like new" knives.
Personally - No, I don't worry about it. If I want a knife to retain value, I don't use it. I keep the knife and all packaging in new condition. If I have a knife I want to carry and use, then I will carry and use it and accept the fact that it is going to look carried and used.
I have over 100 pocket knives, and other than a face-to-face sale to a good friend, I have never sold a single knife so far. I have given away a few. Otherwise, I still have all of my "college textbook knives."
