That doesn't obviate the need for it, as it's required to form a spirit weapon (for Quincy). If you're implying this is not the case, then it begs the question: why is Ichigo the only Quincy that can form a spirit weapon without a Quincy cross, and why is he the only Shinigami that can form a Zanpakuto without an Asauchi?
