I don’t know a single person who would marry for that sort of reason. But the people I know weren’t under any pressure to get married. Some of them are single, some are in long term committed relationships with kids, and some are married.

Maybe if you live in a subculture that expects people to get married by a certain age this is an OK take. But it’s so far from what I see that it seems like a really niche perspective on a complex cultural institution.
