I think they meant to say a specific "account" rather than getting into person-hood. I have been wanting what the op describes for a long time - why do we have to "create" accounts? Why can't we simply tell the site our account with our request. For a dumb example, having "?publicKey=(key)" in the url. That way the site can know who we are and be able to link our profile, provable by our ability to sign using the private key, does away with login forms, does away with password recovery flow, does away with email single-point-of-failure, allows us to switch profiles easily, etc. It's mind-boggling that every site in the world rebuilds login logic.
