Three considerations are missing;
- sleeping around used to be frowned upon, not encouraged by every medium of popular culture (easier to sell things to insecure single people), and blame was assigned correctly for the fault in a marriage, we had standards to aspire toward, the words of the very vow itself used to be legally binding
- adultery used to be a crime, this kept levels low and it was enforced, the concept of honour was legally binding and slandering a woman’s chastity was criminal (criminal libel and some bitchy specific forms) kept ugly girls from cutting pretty ones down with lies and gossip in the MMV/SMV
- obtaining divorce wasn’t the proviso of a family court “judge” but a criminal one, with a high standard of proof required to leave, divorce was rare
It is THESE things, which kept people in line and made them treat marriage seriously.
I would endorse a two-marriage cap for life (excepting widowhood). Fool me once… choose wrong twice….
Both sexes had legal protections when times were good.
Age limits to make a choice of marriage partner accounted for maturity, income, religion etc. Good matches.
From a female perspective (wait this isn’t vapid), I think women have displayed some new male-like traits in selection for good reason e.g. more emphasis on appearance, fitness and wit, because the excessive overpopulation has left us so many to choose from. We’ve always been as shallow as men (if you had to choose between two people equal in other ways but one is hotter everyone would choose the hot one come on), but now we have a lot more choice and men have to jump hoops but for dates instead of courtship and marriage. Women aren’t locked down into those choices and assume fertility is a given because of our sex. Most men nowadays are fat or not fit, so the healthy toned man is maximising his fitness signal, similar with symmetrical, masculine appearance in a world of antiandrogens, phyto and xenoestrogens. It’s like a nuclear bomb of a signal in that case:-

I’m normally totally level-headed around men but this level of genetic fitness has a profoundly distracting effect even upon me which I can only compare to Kate Upton’s bouncing tits in a wet t-shirt as an effect on men.
PC quashes genuine wit and makes it shine the brighter in bleak times and so on.
Lust is the desire to breed after all and we shouldn’t forget this, it can be a positive force. If you want to incentivize marriage, make a man invested in his children (and certain of paternity because he loves his wife) and a woman invested in her husband and his attentions (and her children because duh).
As for the warning at the end, the traditional women don’t live in that traditional society. The men are too poor to even consider marriage. Hardly a choice. A woman who waits around is going to be kept waiting forever because men think they can get the same quality of woman regardless of age.
