(The rest of your message, here elided,  down to  "====" seems to be 
based on a misunderstanding of the term "network information object" in 
HTTP. It is what you call "abstract resource", I think, so arguing that 
a URI identifies one or the other makes no sense. I think you have
a consistent model with Roy's and with mine, but you attach different 
meanings to the terms we use.)

Agreed.

For that software, my interpretation of REST and Roy's serve equally 
well.

The RDF core group and I and certain others seem to agree on best 
practices for RDF
identifiers, and as RDF provides the only test cases where URIs are used
to identify arbitrary things, I suppose that will stand in practice.   
It may well be that
philosophical discussion which is not base on test cases will as you say
just waste of time.

PS: In another message I have responded to Roy and Mark with a test 
case.
