It's more than Obito could use. Besides, Madara used that MS once, and just to get to Obito. For all we know, he could become intangible as well.

Either way, Obito's inability to become intangible is something to do with him, not some fundamental law. Since he clearly lacked the willpower to subdue the Juubi fully (as a simple attack tore out the Biju, unlike say Madara), it seems logical to me that that also prevents his intangibility.
