Oh I agree with you. If I thought someone might actually try to kill me (not just hurt me), a restraining order is the last thing I would get. I'd go into hiding instead. But I understand that to be the theory.
This person knows where you live, where you work, who all your friends are, your family.
Yeah, right. You are expected to quit your job, take your kids out of school (who are possibly also his kids), move hundreds of miles away, and possibly still not get away because they are following you around. On a whim. Oh, and never contact your friends and family again, they can be watching.

Not an option for some people. You need savings and cash while hiding. What if you have children, can you just pull them out of school (say), while you hide? How long would you hide for? 5 years?
No necessarily, the custody issues might be solved. e.g. what if a couple (with kids) break up due to the husband beating the wife and kids. Father gets no custody and there is a restraining order to prevent him contacting them (y'know so he doesn't beat them again).
