This is totally inaccurate. It's perfectly reasonable to store
user-specific data in Resource objects.  "a Resource is a page that
can be generated for different users" is either irrelevant or not
true, I can't tell which. You can dynamically and return Resources
based on which user is making the request.

Now, I'm not sure my favorite abstraction for a user is a string; I'd
probably pass something other than a username to a Resource. Perhaps a
rich object representing the user.
