I think what is relevant here, is that there is a separation between the inside and the outside of the black hole. Since there is no communication between the two, on the inside it could be anything. And its not just the matter and space, even the laws of physics might be completely different. If it weren't so, then there had to be a "super-space" that communicates how ordinary space behaves on both the outside and the inside the black hole.
