Agreed, If we assume that the properties that are attached to a bob are 
not sufficient to uniquely identify it, then the state should not be 
used as a means for identifying bobs. In other words, two bobs that 
refers to the same state of the same entity, may have different identities.

This raises the following question: Do we need to (uniquely) identify Bobs?
