That's an interesting article, but I think it misses an important part of the historical origins of the word woman.
Wif-man indeed was the origin, but the "man" in that sense didn't mean a bloke, it meant human, or person.
A man in the sense we mean today was a were-man, the "were" surviving in the word virile, and of course werewolf.
A woman wasn't being compared to a man linguistically, they had equal grammatical standing.
