There is a third possibility, Hans: Owners who take care of their stuff! And for themselves, not for the next guy.
In fact, there are probably as many possibilities as there are people.
I have never thought of guitars as an investment. I've never, ever worried about, or even given a moment's thought, to resale value. Resale value is irrelevant to me, despite the fact that I've bought and sold many. I don't plan on selling them, it just seems to happen sometimes.
I take care of my guitars because I enjoy OWNING pristine ones!
And certainly not to build a collection, since as you know, I am not that guy.
Example of my habits:
In the past I had expensive European cars I kept pristine enough to participate in concours events, but I also raced those very same cars on the track. You want to tell me I didn't OWN cars I drove on race tracks?
Come to think of it, my brother won several autocross championships with his immaculate 1973 Lotus JPS that he bought in 1974. It's also been his daily driver to this day! I would say he owns the car after 38 years... But it still looks new. He's his own PTC.
Any guitar I have gets played on sessions for my livelihood. All of my studio equipment gets daily use. But I take really, really good care of it. Which is not difficult, and requires no special treatment beyond being a bit careful and fixing anything that goes wrong. I have preamps that look new after 20 years in the rack. Does it matter that they look new? I own those preamps.
Owning a instrument, and keeping that instrument in pristine shape, are NOT mutually exclusive. I OWN my guitars, dagnab it.
You don't own a car any less if you have a dent repaired do you? Or if you wax it? Why would you feel that you have to keep dents and scratches on a guitar when they, too, can easily be repaired? One day your daughter may dent your car. You gonna keep the dent to remind yourself how cute she was at 16?
Nor does one drive a car carelessly in order to "own" it.
The whole categorization of owners vs. caretakers is pointless, since everyone's habits are different. Why the need to generalize?
I completely agree with Markie!
Yeah. I'm an OWNER. And my guitars look freakin' GREAT.
