If you read the article, many of these women who desired to get married had numerous suitors, but these suitors were judged unfit for one reason or another and thus failed to meet the women's strict requirements. Much like companies wanting to hire 100x developers at 30$ an hour, these women are unfortunately trying to bend the supply/demand curves to their tastes, rather than working within the reality of the market.
As an aside, marriage as an institution in western societies is now a legal quagmire [1]. It's legal roots were laid down in times when women did not earn much and did not vote, so they were paid very generously in case of a divorce whose fault could be proven. Nowadays, divorce is the single most powerful legal instrument to take half of someone's net worth without any reason whatsoever. Marriage as an institution is beyond repair, and any couple who supports the spirit of family unity should boycott legal marriage for their own sake, as it leads to extremely toxic financial incentives for the lower earning spouse.
