You can buy a replica of a piece of art to look at it. You buy the original to store value. You hope it may appreciate as well. It could end up worthless. But until someone says otherwise, it has the value stored in it.
It's just like baseball cards. You can make unlimited indistinguishable copies, but you don't. The date they are printed matters for some reason. Who owned it previously, its last sale price at auction is part of its history and thus its value.
Sorare/ubisoft also has a much better value proposition. Theyve combined draftkings and pokemon into a live betting market with collectable cards that you can use to play a game, to win more. The early generation may be simple digital art, mostly worthless, but there will be more innovation to come. Part of the reason I think NFTs are the real deal is because I think the value of art is often stupid, and yet it still has value. Even if 99% of NFTs turn into nothing, there will be some early art from people that arent famous yet, that is someday found. I have no doubt there is an immense amount of mystery being planted, waiting to be uncovered. Whatever stupidity and hype and storytelling and history around artwork, that I dont understand, will translate to this realm as well. The lack of decay, fire damage, traditional theft, and loss will be an interesting wrinkle.
