Even the most widely accepted use case which is crypto-currency fails to break out of the theoretical value outlined in the different white papers. I own several crypto-currencies and there hasn't been a single moment in which I thought of buying something with a crypto-currency. I have crypto-currencies because I'm speculating in their asset class value, not necessarily because I'm betting on their utility.
Now, I know that crypto coins are indeed used in real service/product transactions, but I think there's a difference between the present economical use of cryptos and its potential mainstream use where cryptos can effectively replace fiat currencies in super wide economic settings.
I believe that Web3 would happen but I honestly can't see a clear trajectory for Cryptos, NFTs, DAOs etc to become effective instruments that can replace existing Web2 instruments.
In fact the reason why everything in Web3 feels like BS right now is because everything in this space uses Web2 distribution. People promoting NFTs on Twitter feels a little bit like someone faxing you a webpage. Owning the rights to a random JPEG is something that feels too abstracted from the present Web2 mental model and value proposition.
