Sure, your current reasoning has convinced me to accept octopi. But by this reasoning, you're the one suggesting, against your present justification, that octopuses is not a "correct" plural (and should be corrected to "octopi"), when its in "recent popular usage". In which case there is no use for the comment I had replied to.
