Tell that to those crazy rich people who has nothing to do with their massive excess money, but to create non sense luxuries to sell It to their fellow rich people and then create a hype on the latter so people catches their attention.
That's the secret to every successful business.
Create a name and hype and people will start buying your product, all perfectly the same as those NFT digital arts, they are useless and expensive. I'd rather have an expensive art that dont exist in a digital world for collection purposes.
