I don't think you are the point the OP is making tbh.Ok, the moral dimension escapes me. Is it Catholic guilt, Protestant shame—I can't always remember?
Speak for yourself though. My audio purchases are few in number. I haven't bought 'far too much' overpriced stuff, nor selected exclusively lowest-cost stuff.
I'll likely pay a premium for industrial design, aesthetics/haptics and UI/UX where applicable because I value those things. So there's still a cost-effectiveness evaluation but not limited entirely to the sonics. There's also the possibility that the vendor will be around and support the gear in a decade or three to consider. And so on.
Now all that could be considered snobbery by some definition, but argumentum ad lazarum is simply reverse-snobbery, a virtue signal of its own.
The OP isn't about "premium" stuff that's well built, well designed and fits into a reasonable cost-benefit curve.
I see the OP is more about equipment that's luxury for it's own sake.
