LOL, they do!
Always thought it was weird, but kind of understand it now. I have one very nice guitar, that is so nice, that I get nervous touching it and have OCD to wipe it down every time I get it out for a while. Bought it from a friend who lives in Japan. I'm afraid to take it out anywhere. It's gorgeous and plays like a dream.
But a few years ago, was offered a killer deal on a new Gibson 60th anniversary Custom Shop 1960 Les Paul reissue. It came "lightly aged". I have no "first nick" trepidation and pull it out to play with ease. I'll even take it out to a jam or what not.
I've always made my own patina, but it seems to take decades. The most "patina" of mine is a 1984 Fender Esprit, and it already had some significant marks when I bought it in 1988.
