Kamui is still a technique. I always figured it was just a matter of skill. Kakashi never managed to become intangible. Obito couldn't phase as the ten-tails. Just a matter of skill. Plus it fits. Madara is the Ur-Uchiha, the reincarnation of Indra, and the puppet of the grandmother of all ninjutsu. If anyone would have the skill and knowledge to pull off a trick above the original owner it'd be him.
