That seems very focused on cryptos. Isn’t web3 mostly the use of serialized and decentralized data stores, eg blockchains? Edit: thanks for the downvotes, but

  "crypto" and blockchains are inseparable. If you don't need the double spend protection, then it becomes just a plain old cryptography. You can imagine the next web as whatever you like, but "web3" has been advertised in the specific context of Ethereum and its wannabees. We've already had DHT, Bittorrent, SSH keys (== log in with a "wallet"), Certificate Transparency, self-hosting, federation, Dat, OpenID, GPG and web of trust, and many other primitives for decentralized identity and distributed storage that weren't "crypto".

    Ethereum is mentioned, because it has Dapps (iirc). But I don’t think you necessarily need the monetary part in order to use the blockchain to store stuff and execute procedures as a reaction to certain values. That’s what I think “smart contracts” are. I remember that IOTA has a similar function and you can send zero value entries, specifically to communicate between low power iot devices. If you really need a blockchain for most applications is a different topic though.

      Using a blockchain for storing stuff without needing the double-spend protection is like using a car to just listen to music on the radio, without the driving part. You can do it, but it's a wasteful overkill.

        You don’t use the blockchain to store, you use it for distributed version control.
