My wife, as a musician, has similarly strong feelings about people collecting Guitars (and other instruments), there is nothing more depressing than an instrument sitting there unused and just looked at.
It probably wouldn’t work for any instruments more fragile than a solid-body guitar, but I’m really glad to have had the experience and I wish there were more opportunities to do the same with other musicians’ gear hoards.
I'm all for that attitude
(Sometimes, collectors who own valuable instruments lend them to accomplished musicians, perhaps even on a long-term basis. I think that's admirable!)
