Because sealing a chakra construct is very different from sealing an organism that happens to possess chakra. These are obviously entirely different things. The translation also says 'enemy' NOT 'anything'. Also, when TTJ-Madara attacked Obito when he realized Obito was stealing his chakra, Obito had already broken off PHYSICAL CONTACT with Madara, with only Madara's chakra connecting those two. So this still doesn't prove that Obito can physically attack Madara while being intangible.
