The Origin of the Patriarchy?

Stilted old English translation but this story from the Mahabharata (PG-13) makes one wonder why the supposedly patriarchal oppressive Brahmins who are supposed to have manipulated the epic for their evil, cunning purposes, preserved this story.

"Vaisampayana said, 'Thus addressed by his loving wife, king Pandu, well-acquainted with all rules of morality, replied in these words of virtuous import, 'O Kunti, what thou hast said is quite true. Vyushitaswa of old did even as thou hast said. Indeed he was equal unto the celestials themselves.

But I shall now tell thee about the practices of old indicated by illustrious Rishis, fully acquainted with every rule of morality. O thou of handsome face and sweet smiles, women formerly were not immured within houses and dependent on husbands and other relatives. They used to go about freely, enjoying themselves as best as they liked. O thou of excellent qualities, they did not then adhere to their husbands faithfully, and yet, O handsome one, they were not regarded sinful, for that was the sanctioned usage of the times. That very usage is followed to this day by birds and beasts without any (exhibition of) jealousy. That practice, sanctioned by precedent, is applauded by great Rishis. O thou of taper thighs, the practice is yet regarded with respect amongst the Northern Kurus. Indeed, that usage, so lenient to women, hath the sanction of antiquity. The present practice, however (of women's being confined to one husband for life) hath been established but lately. I shall tell thee in detail who established it and why.

"It hath been heard by us that there was a great Rishi of the name of Uddalaka, who had a son named Swetaketu who also was an ascetic of merit. O thou of eyes like lotus-petals, the present virtuous practice hath been established by that Swetaketu from anger. Hear thou the reason. One day, in the presence of Swetaketu's father a Brahmana came and catching Swetaketu's mother by the hand, told her, 'Let us go.' Beholding his mother seized by the hand and taken away apparently by force, the son was greatly moved by wrath. Seeing his son indignant, Uddalaka addressed him and said, 'Be not angry. O son! This is the practice sanctioned by antiquity. The women of all orders in this world are free, O son; men in this matter, as regards their respective orders, act as kine.'

The Rishi's son, Swetaketu, however, disapproved of the usage and established in the world the present practice as regards men and women. It hath been heard by us, O thou of great virtue, that the existing practice dates from that period among human beings but not among beings of other classes. Accordingly, since the establishment of the present usage, it is sinful for women not to adhere to their husbands. Women transgressing the limits assigned by the Rishi became guilty of slaying the embryo. And, men, too, violating a chaste and loving wife who hath from her maidenhood observed the vow of purity, became guilty of the same sin. The woman also who, being commanded by her husband to raise offspring, refuses to do his bidding, becometh equally sinful.

"Thus, O timid one, was the existing usage established of old by Swetaketu, the son of Uddalaka, in defiance of antiquity.

Shvetaketu, son of Uddalaka, might be a historical figure (that is, if the ancient Hindus had history :) )

And Pandu was informing his wife Kunti that the practice of Niyoga was legitimate. In the Mahabharata, Dhritarashtra, Pandu and Vidura are the children of Veda Vyasa (traditional author of the Mahabharata), by niyoga.
