@kaia History is filled with examples like this. Rich arseholes love rare stuff BECAUSE it's rare. I've had caviar. The 'good' stuff, too. There's nothing special about it. It's just exotic and costly, and that's all there is to it.
Black pepper was once treasured by rich arseholes, too, until it became common. It's never been about the thing itself. It's about feeling special because you're rich. It's the most childish, primitive motive.
