I've seen people purchase the weirdest things for unreasonably high prices. It's almost as if some people have money to burn. This happens a lot in the gaming world where people buy a digital sword for example for a couple of grands just so that their game character can look fancy

Buying skins is very common and normal in our society, it's costa a few bucks in most games, you play, look cool online and get some fun but I don't understand why people buy so called
rate satoshis and pay lots of money. By the way, I still find logic here, it comes from Satoshi or someone else important and you want to hold piece of it but it's still stupid on my mind, it's a virtual thing, what can I do with it? Who checks if I hold a piece of coin that was into someone's wallet a decade ago? It's basically starting looking for a $100 banknote that has been touched by George Bush.
Every satoshi has its own unique name, number, and place in the blockchain. It also has a history of where it has been. These are all attributes that can be used to make something collectible. These factors can lead to extreme rarity whether you agree or not. Those are facts. Whether it catches on is another question.
Also all of this satoshi data can be looked up and verified all the way to the final satoshi that will ever be mined. The data has already been created all the way up to the final sat that will be mined.
If you want, psychologically you are capable to make everything valuable. If Messi blows a balloon, some might pay thousands or millions of dollars because that's air that Messi breathed and this way you can make non-fungible even air but that's definitely crazy.
