Hi Devil,
Let's take one specific hypothetical example: let's say you have a 17 year old neighbor named Steve, who happens to be a devout Jehovah's witness. He comes and tells you about this 15 year old girl named Mary from his congregation that he really likes and can't stop to think about. He tells you he is virgin, has no intention of ever having sex outside of marriage, that Mary told him she is a virgin, and that he really wants to have a family and be a great dad. Then asks you for advice on what to do. Will you tell him to just forget about Mary, fatherhood, sex, and just live a celibate life including the next 20 years of unsatisfied high sex drive ?
My advice to Steve would be to propose to Mary, marry her as soon as legally possible (Nevada allows youngsters to marry), and, if the first night he finds out she is not virgin, get the marriage annulled the next business day, and reduce all interaction with her to "hi, how r u ?". And that, if she is indeed a virgin, try to stay married as long as possible, and to take the red pill and learn game to keep his wife's interest in him alive and lasting.
By the way, the right statistic for that situation is here:
The Social Pathologist: Sexual Partner Divorce Risk
The divorce statistic within 10 years for couples where the bride is virgin is either 25% or 19.53% (not sure on how to read that chart). For the above described situation above, I believe it's much less.
The 50% figure you quoted includes marriages of singles moms with kids, who have lost their ability to bond, are in search of a wallet, marry the man that comes with the wallet, and after a few years realize that the man no longer has to even come with the wallet. That they can have the beta free wallet to spend as they please. The 50% also includes alpha widows marrying betas just because they can't pin down an alpha, and then spend their married years longing for (and sometimes getting) alphas, and then realize they can keep the wallet without having to put up with the beta anymore. So that 50% figure is irrelevant to the above described situation.
You have made many other points, but I prefer to just answer one at a time, so the post doesn't turn into a novel.
