Geoff: 
1. We can't know that salt wasn't used in Paleo times. In fact, given
patterns of population migrations suggested by genetics, Paleo people may
well have moved along sea-shores. If they were hunting and gathering their
foods there, it is very likely that they were eating considerable salt. 
2. Please read the article in question. Taubes says that recent evidence
suggests that eating too little salt may pose health hazards to some.
