Time spent dating, or in a long-term relationship, prior to marriage is positively correlated with enduring marriage. That is, people who date each other for 3 years or more prior to marriage are 50% less likely to get a divorce than those who don't[0]. Thus, it pays societal dividends to encourage people to take their time and really get to know each other before getting married. Saying "the sooner you get married, the sooner you get your money back" or worse still "stay together without getting married for too long, and you risk not getting your money back" specifically discourages the behaviors that prevent domestic violence (including child abuse). What I believe we want is marriages that uplift their members, and minimize spousal abuse. Making people feel like they can't afford to not get married is the exact same phenomenon that drove up domestic violence during the COVID lockdowns[1].

If you're telling me that more abusive marriages is better for society, I don't think we have enough common ground to discuss this.
