It is optional, you can live with scars. You are just choosing to take them.
you can live with all kinds of things that people take medication for. weight (not necessarily implying that the medication really helps), erectile dysfunction, low testosterone, AIDS (that one is a stretch, considering how dangerous it is)
they all hinder your life, though, and even considering the possible crazy side effects of most of them, it's usually worth it. it's fine to complain about the side-effects
