I don't think that I'll be able to change your mind. I get the bad blood with crypto, really, but I guess I just don't share the absolute conviction that the whole thing is a scam.
The way you're breaking down ownership is true, but it's true about every form or ownership. The deed to your house? You don't own anything, that's just a piece of paper that someone says prooves that you have a right to live there. Whether that's saved in a county records department or a blockchain that doesn't really change. Point taken, but I think it's a broader point than how you were using it.
I'm not really sure what makes saving your deed information on a blockchain less valid than in a county records department though. I mean breaking it down, a blockchain is really just a ledger that keeps track of information in a cryptographically secure way. I think that this has gotten out of hand because of all of the get rich quick schemes, and that's fair. It's happened....a lot. But does that invalidate the whole endeavor?
The current exchange system has rent seeking vultures sitting on top. Visa, MasterCard, these fuckers sit there and take a percentage of every transaction that theY fascilitate. What are they doing? Keeping a ledger. We trust them to do it accurately and pay them steeply to do it. Now we have a self managing ledger that requires no trust from anyone. Can you really tell me there is ZERO use case potential here?
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.
