So, what is it? Are you for the current system of justified legal compensation (alimony etc.) or against it?

You know, in my country, from after the marriage, women's lives are controlled by her husband and his family, the rule of the religions, culture and the society. So, given I have a very supportive parent and another not-so-unsupportive parent, I never wanted to marry and give up my freedom and choice. So, I never really related with the women and people in general who wanted to put a ring on the relationship as soon as possible. But, then I hear from guys like you and now I understand why the women want the protection of marriage so desperately. Even if the society doesn't let women to br sufficiently equipped with education and skills to be eligible for the labor market and even if it hold women back from entering the paid labor market by burdening women with all the domestic and care work, it at least upholds an institution (marriage) which will kind of legally guarantee that the man financially compensate the woman for her time and energy she put behind him and also compels the man bear the financial responsibility of the woman and any kids born from their sexual interaction. And that is exactly why so many women want to marry and not stay in a relationship with all the responsibilities and expectations as marriage but without the security of it.
I won't call marriage an ideal system, it's not. But until and unless, our society achieves a strong and almost irrevocable gender equality, until and unless women are deemed as just humans with all the needs and wants and not just mostly as the second sex everyone can use and mold or throw away, I would support the legal protections of modern marriages.
