I currently believe no-fault divorce is bad because (content warning: right-coded language) it destroys the sanctity of marriage, because any wife can just decide "I want a hotter/richer/higher status husband" at any time, and dump her husband - and of course, husbands can do the same, and the same goes for same-sex marriages. True, the one who earns more may be somewhat disincentivised by alimony requirements, but this isn't an insurmountable obstacle for everyone.

It makes marriage no different from a long-term relationship, just with a meaningless, ridiculously-expensive ceremony.

Will my mind be changed by the end of 2023? You can attempt to change my mind in the comments below. I am currently slightly sympathetic to some arguments for no-fault divorce, but currently not enough to change my mind.
