FWIW, I'm probably as much opposed to object identifiers and logical pointers as you are, but the claim that they are somehow not logical is such blatant nonsense (unless you start redefining the notion of "logical" such that it becomes trivially true) that it makes me cringe when it's used to defend the relational model.
