It seems to me like collectable pokemon cards, where although you have a few extremely high value one's for either rarity or special circumstances, when averaged out, even these astronomical values don't have much of an impact to make it a worthwhile market.
As for other NFTs, it will be successful if the technology is used in a natural way where it is the most optimal way to manage the service. Otherwise, it will simply be a gimmick.

I am not sure if all of these items sold for thousands and thousands of USD will have the same high value after 5-10 years.
I would argue it's highly unlikely as there's very little cultural meaning or artistic value, and trying to play the NFT market at least currently is playing the lottery and heavily not worth the time.
