I think there may be some confusion.

"Authentication" here does not refer to "Does the user authenticate
themselves to the site" (e.g. do they log in), but "Is the site you're
talking to the site you the site you expected" (or, put differently, "Does
the server authenticate itself to the user").

Without authentication in this sense (e.g. talking to whom you think you're
talking to), anyone can trivially impersonate a server and alter the
responses. This is not that hard, a few examples for you about why
authentication is important, even for sites without logins:


This is why it's important to know you're talking to the site you're
expecting (Authentication), and that no one has modified that site's
contents (Integrity).
