Because at some point gravity just crushes the cave? Its not that there are no caves known deeper than that, its that there's a depth beyond which cave formation is *impossible* and supporting a tunnel structurally is *impossible*. The only reason magma pipes don't collapse is they're filled with magma, which is really dense.
Edit: before someone says it - if Agartha has magic powerful enough to achieve such a feat, (1) why are they bothering with the surface world? (2) Shouldn't they be able to move anywhere on the map from any territory? (3) They've already won, their magic is so awesome.
