A meaningful discussion would arise in comparing the cost of a camera, not to the cost of a wine, but to the cost of making that wine: Grape selection, crushing, casks, testing, blending, ageing, etc.
An experienced vintner spends money with a target of a wine with particular level of quality. A camera maker does the same thing.
Are there snobby camera buyers in the same way there are snobby wine drinkers? Sure.
Are there drivers incapable of exploiting their high-performance cars, just as there are photographers who can't exploit their high-performance cameras? Sure.
