I don't think the worry is that we will suffer a Black Plague again, but more than almost every instance of surgery or anything that leaves a person immunocompromised will lead directly to infection.

A lot of modern medicine suddenly becomes useless because the health benefits that it brings are nullified by the fact that an infection is sure to follow.

Organ transplants and chemotherapy are two big ones that become near impossible if antibiotics are useless.
