Well, I do see the possibility of having every edge an individual, so I 
probably should have written

e1 me:statedBy_1 "T. B. Passin"

to hint at that.  It seems to me that the kind of "recursion" you are 
talking about here is not a problem with modeling properties as 
individuals at all, but rather of an infinite regress of statements -

Tom said "X", but he was wrong, that's what Eric said today, but Mary 
disagrees with him ....

The problem, if that is what it is, lies in the things being stated and 
not in the individualness of specific RDF properties.

Or maybe I didn't understand what you meant.
