Well its the basis for transfinite induction. Without the
axiom of regularity there wouldn't be transfinite induction.
What text books are looking at Dan-O-Matik? Do you at

It is not an axiom used even indirectly in most, even advanced math textbooks. Whether or not a particular set is an element of itself is rarely if ever an issue in math textbooks AFAIK.
