If I was stuck in the desert with no water, or a brush, or a rag, I'd be a lot more worried about other things. No need to OCD out about grit in your knife if you've got those problems.

Here's something interesting, ffwd to 4:10 in or so, and look at how much actual grit and grim is in the mechanism with the guy trying his hardest to cake the knife up. It's nothing, a minuscule amount that could be washed out of even a pinned together folder with no trouble.
It's a gimmick. If it was a huge thing that everyone wanted, you'd see other manufacturers rushing to have their own ez-strip models/lines.
In the end, mechanically, the modern knife buyer usually wants - 1) Improved lock strength, 2) Simple fast opening, 3) Smoothness. That's where the "arms race" has been in terms of construction the last 50 years or so mainly. Being able to pull apart your knife without tools is way down the list.
