Your second paragraph is where I think the win is. When you have self custody of things, you have more ineroperability and stuff like that. Largely I buy the statement that all this is a solution in search of a problem. I don’t think that’s necessarily a bad thing though. It broadens the possible space of options in the future, which I find to be exciting.

Edit…added the following.shit

There is at least one airline using this NFT model currently, in Argentina I think. It could be that the CEO is using the service because he’s just a crypto maximalist but I believe the win from their point of view is that they get a cut of subsequent secondary sales. They’ve sold the ticket once, maybe you can get a bit more for it.

As far as the card game goes, what your saying, that the game could be shuttered is not different than what we currently have. It’s only different in that you’re able to own the cards while it’s running. Maybe you want to gift your child a good card that you have, you can just send it to them. Impossible currently because you don’t control anything in hearthstone except how much money to spend on packs.
