Because the thread is stupid. What nikka is going to build an entire house? If he can "provide", he'll simply pay someone to build one or buy one that has already been built. That's that "provide" function that makes a man a good husband.
A woman should be able to cook a good meal, just as a man should be able to protect and provide for his family.
Women nourish and nurture. Men protect and provide.
A woman who cannot nourish and nurture is worthless as a wife. A man who cannot protect and provide is worthless as a husband.
