The number 1 is not unique.  If you have a 1 in your computer
and Dan has a 1 in his computer, and I refer to the number 1,
then which 1 am I referring to?

The point here is that the triple is abstract.  What you have
in your computer is a representation of a triple, not the triple
itself.

Giving a URI to a triple will not help.  You'd have to decide if
you the URI named the triple - i.e. the abstract thing - in which
case you have changed nothing, or a particular representation of
a triple, in which case you don'thave a means to refer to the
triple.
