I answered in jest the first time, but I kind of feel you. Sometimes I feel bad even for having my MIA Fender when right now I mostly only do charity and church gigs, with a few scattered bar gigs. But I'm slowly getting over it. I can afford it and I can enjoy it, what difference does it make if I don't use it to make money.
I don't know if I'll ever buy a boutique bass, and if I did, I don't know if I'd ever let it leave the house... but it's still a possibility if my finances are in order and I play well enough to really use one. Don't feel guilty! Shoot, I'd feel accomplished. It means you're financially stable enough and/or musically talented enough to warrant one. Those are Life Goals!
Sometimes I go to car shows to remind myself that people put $$$$ into their hobby with no expectation of needing to be skilled, rich, or a professional in need of tools lol.
