The "own" part is a fantasy. Fractional tokens of the world's grain resources, on-chain video hosting, a global decentralized currency exchange, etc... none of that really scaled. Having a secret key to a wallet is not more "ownership" in practical terms than having a bank account with an ID and a password.

The way I understand web3, is that its key promise was to create a trustless global digital environment. Technologically speaking, it works to a large degree. Pragmatically—I don't think it's top of mind for the vast majority of people, including most (ex)web3 advocates.
