Can you explain *why* you think literals should not be permitted as
subjects?  The rationale you have given above sounds like it is saying
that literals should not be subjects because RDF does not permit
literals to be subjects.  

IMHO, RDF should allow "anyone to say anything about anything" -- not
"anyone to say anything about anything . . . except a literal".
However, if you see some specific harm in permitting statements about
literals, please tell us what that harm would be.
