That's not really a logical argument. There are also plenty of people who can afford such luxuries and are willing to pay for them. Chastising people on the forums for their buying choices is never a good platform to pitch your argument. The same applies to those who 'poverty' shame others for not paying more to get a better card.
Is the card worth the money? Not by a functional metric, but Nvidia pitch it as a halo product. It's just how it is. And blaming individuals for purchasing it is futile, especially when they get bought by businesses en masse.
