We haven't seen too much physical world got into NFT have we? I mean I am %99 sure that there must be plenty of shirt companies that already ripped of the designs of big NFT collections and printed all of them, specially the most rare and expensive ones. But that doesn't change the fact that we do not see plenty of people wearing them everywhere. I go out, and see zero NFT's in real life, in shirts, in billboards, in logos, in nothing basically.
It means that the "ownership" of NFT so far has been only "buy it or mint it early, and then sell it when it goes up" and not really nothing else. When people start to "use" it, then we may see it go back up.
That is going to take a while before it could happen. Not saying that it would never happen, but the idea of NFT is basically something digital, so having a physical corresponding to it makes a bit of sense but not too much. This means that we would have to just wait for it to eventually happen. Like for example you could make 10 thousand NFT's in a collection, and also have tshirts for it as well.
Projects that make their NFT's like 500+ dollars, could afford one shirt, each of them have different design of course, and could ship it to anywhere in the world. I guess MAX it could ever cost would be 100$ each shirt, and I doubt it would even that much. Project would still be in profit. Don't know what happens when you sell the NFT and keep the shirt though. Maybe a promotional thing for people who mint, and not just own the NFT and buy from someone who minted it.
