That's like saying Nine-Tails Chakra Mode could count as Naruto's base form because he had that much extra chakra just sitting him on since birth.

Sharingan is an extra. He can function perfectly well as a ninja without the added benefit of the Sharingan, and he can do so much better than Naruto can.
