I don't need to prove anything. Grafted is not a requirement for receiving Hashirama's cells. You are also the only stating that Naruto's arm is different from others due to a different arm just so your theory on Sharingan doesn't fail. If human's having two eyes was against your theory, you would argue against it. Sorry but Momoshiki's prototype is not Hashirama's arm. Therefore, you have no proof what even the arm is. You can't say Naruto's arm doesn't have Hashirama's cells because it isn't "grafted" on, cause where's the proof? Our proof, the arm is stated to have Hashirama's cells and stated to be connected to Naruto. That's all we need.

Oh, and by the way. Your argument fails since it's explicitly stated to be made from Hashirama's cells therefore living tissue.
