"みんな少なくとも一度は結婚すべきだと思います。そうすることで、どれほど馬鹿げていて時代遅れの制度であるかを知ることができます。"

Simplified Meaning:

Marriage, according to the quote, is seen as something old-fashioned and not very practical in today’s world. The idea is that by experiencing marriage, a person can truly understand how it may not fit well with modern lifestyles or individual needs. For example, imagine buying a very old typewriter because people used to say it was the best way to write. After trying it, you realize how much harder it is to use compared to modern computers, making the old typewriter seem outdated. Someone might think marriage is essential because of traditions or movies, but seeing it firsthand could change their viewpoint. They could feel that living together without the pressure of marriage is more suitable. By experiencing marriage, they get a clear understanding and can decide for themselves whether it’s right for them or not. The quote suggests that marriage may not be necessary and wants people to see and understand this themselves through their own experience.
