There are more weapons that can kill a deamon, take for example the sword of Asuryan ,it is stated in the novel that his sword can permanently kill a deamon, deathsword also, the psyker theory holds but only if the psyker can obliterate  the whole deamon in its entirety (hightly unlikely) but someone like the emp could do it (he destroyed horus's soul completly so i guess he can do the same to a deamon) also i think that parriahs unleashing their power directly on a deamon's very essence would also anihilate it completly. Oh and one more thing Khorne Nurgle and Tzench where fully formed by the time the last old one died.
