The only justification I’ve ever been able to think of is Pokémon. The idea is supposed to be that every Pokémon is unique but there’s actually only a limited set of variables to define each individual ‘mon. I can trade you a Zubat I just caught and it can be identical to one that I first caught in Fire Red twenty years ago and have traded through every game since.

If each Pokémon was truly unique and on the blockchain, it could be meaningful in ways they currently aren’t. There could be only one Coalossal that Wolfe Glick won the Player’s Cup with. He could trade it away for charity and someone would pay for it. I could trade Pokémon away and track them as they’re traded around the world.

It’d be cool. But it would not meaningfully make the game more fun. And it’s Nintendo so they’re never going to do blockchain. And that is the best pitch I can give you.
