Let's be sure we mean the same thing by "resource".

*Anything* can be a resource, whether it is named by a URI
or denoted by an anonymous node in an RDF graph.

However, if we are to refer to a resource in a way that is
significant to either the web or semantic web machinery, then
we need to use URIs, URIrefs, or anonymous nodes.

I.e. in section 2.2 of AWWW, it says 

"By design a URI identifies one resource."

The thing identified does not become a resource because it
is named by a URI. Rather, we use URIs to identify resources
(which exist regardless of how we refer to them).

Agreed. The URI used to denote a resource should be distinct
from the URI to denote its representation (unless, of course,
the resource and representation are the same -- as would be
the case of the representation of a representation, which
would correspond to a bit-equal copy of itself).
