The causality bounds on monopole abundance are reexamined in the light of recently constructed models which display very rapid monopole annihilation. It is shown that the behavior displayed in these models is consistent with causality, and that the proper formulation of the causality bounds is very dependent on the representation content of the model. By invoking intermediate phases with appropriate types of symmetry breaking, it is possible to annihilate essentially all monopoles, or even to avoid their ever appearing.
