 In SGS (2000), the (CMC) has more the status of an empirical posit. If \(\bV\) is set of macroscopic variables that are well-chosen, meaning that they are free from the sorts of defects described above; \(\bG\) is a DAG representing the causal structure on \(\bV\); and P is the empirical probability distribution resulting from this causal structure; then P can be expected to satisfy MC relative to \(\bG\). They defend this assumption in (at least) two ways:
