Doesn't Izanami only works if the opponent doesn't know himself? After they accept their fate the jutsu stops. Izanami needs to much requirements, i prefer Izanagi, after all it can save your life and the user can always transplant another Sharingan as well.
you act like thats an easy process
Rin was trained in medical jutsu. It wasn't like she did it with a rusty spoon and didn't use anything else. Madara and Obito have been harvesting eyes for so long. Wasn't it stated that it wasn't an easy process though?The eye transplant? It happens all the time in Naruto. Rin did it to Obito in the middle of a war without all the proper medical equipment or assistance. Madara and Obito aren't medical ninjas per se and do it to, its not a big deal in narutoverse.
They both waste one eye but Izanami takes a bit prep and doesn't work on everyone.

Izanami works on anyone using izanagi.
