Uhm.... as pointed out, since the tool stayed with him in death, he could've easily thwarted the entire plot by sealing either a biju or the Statue itself with his Totsuka blade. Since he didn't, i find it doubtful that it could just seal everything. Even Hashirama had trouble keeping the Juubi in place while Obito and Madara needed a special seal to become it's jinchuriki. Even then, the Juubi itself could only be defeated by Six Paths Chibaku Tensei.

So no, the tool can't seal everything.
