Also, Naruto's lost an arm before, so the pain ought to be familiar. Plus, we don't know how well that Hashi arm acts as a prosthetic, but it's permanently bandaged so it can't be a perfect solution. Perhaps it can be more easily removed than we thought, or it never was a perfect fit like with Madara/Obito. Although he does have the same blood type as Hashirama.
