You're completely right, but it's not relevant anymore. Medicine has advanced and society has changed. A handshake or a look between men and women is not seen as sinful or the first step to adultery anymore, because we are civilized now. Male and female spaces are greatly overlapping and we think of women as human entities and not as "a man's daughter / mother / sister" in the sense of, you'd destroy someone else's property.
Couples can split up without one of them being deemed unworthy, women are able to live on their own and can re-marry and they have the same rights as men. There are paternity tests. There is no reason to prefer female virginity anymore.
