If the jpeg is irrelevant, shouldn’t all NFTs from the same contract cost the same? If it’s just a club membership, why would people buy multiple NFTs from the same contract?
1) "I was rich enough to buy a Bored Ape NFT". This is for status relative to people outside the club.
2) "I was rich enough to buy a super-expensive Bored Ape NFT". This is for status within the club, it lets them all know how rich you are.
It's all yuck to me, but people have different motivations.
