I think it also important to recognize that Luxury is not synonymous with quality.
Absolutely - there are plenty of "luxury" goods that are too finicky/fussy/delicate/fragile to be useful. Fortunately in the camera world for the most part that's not true. And then there's some luxury goods that never made sense, like the gold-plated and lizard-skinned RB67. That's like putting a $30,000 paint job on a Ford F150 pickup truck. Great tool, devoted following, but nobody is ever going to confuse it with a Hassy or a Leica. Nor would they want to.
