Well, there are pitfalls for men and women, that is for sure. The current system doesn’t really offer any real security to anyone, especially from stuff like you described.
However, I’m thinking more along the lines of things going really bad (social breakdown/SHTF, call it what you will). If that ever happens, then it’s just not going to be realistically possible for women to survive without men, because unscrupulous men will be literally preying on them. That’s not to say there aren’t some women who could defend themselves, but in general, nobody is going to be able to stand alone in that situation and men would naturally be the best defense against other men.
