Women have traditionally been discouraged from doing these jobs, but none of these jobs requires a penis. Women can do them.
This is a silly argument, as I could just as easily state that you probably don't know how to cook or care for a newborn etc. Society needs these things too.
Outside reproduction, we DO NOT NEED EITHER SEX TO PERFORM ANYTHING.
The point, which you have missed, is that an individual woman has absolutely no need of a man in her life for any reason other than wanting one. We might WANT to have a husband but we in no way NEED one.
That means we aren't going to settle for shitty men, as women in earlier generations were forced to. We will live quite happily without a man if the ones we meet do not meet our standards.
The days of women settling for bad men out of necessity are long gone. This is fine if a man is a good man, because he's going to have no problem meeting a good woman. But the shitty men will have to do better or be alone. Some shitty men whine and cry about this and claim they are involuntarily celibate, but they are VOLUNTARILY celibate -- all they have to do to find a partner is stop being so damned shitty!
