Forgot crypto, my actual bank account and retirement accounts and nest egg are accessible online these days. The login credentials for those are stored somewhere so I really hope they don't invent brain hacking technology to steal those. If you're the type to use a password manager, then I'd say those are the most valuable pieces of data you store. 2FA isn't never going to be totally utterly 100% foolproof so I wouldn't count on it solely to protect what I have.
