Leaving aside the line of reasoning based on the literal reading, the reading according to Shmuel gives us model of thought in which that which is societally expected of women is framed as what women want, by acting counter to which the man brings about the dissolution of the marriage. Boyarin writes on this complex structuring of biopolitics:
Discursive practices related to female desire that appear in the Talmud and Midrash constitute a structure that functions as an equivalent to the "conjugal right" of European legal discourse in terms of the ordering of sexual relations between the genders, even as the structure does so without sanctioning physical force or economic coercion. The hegemonic rabbinic discourse provides for male sex-right paradoxically through a mystifying construction of women as being needy for sex and of men as being primarily service providers to their wives. [...] In other words, through the construction of sexuality as a form of husband taking care of the wife's needs and through the construction of her needs as both compelling and in part inexpressible, virtually the same effect in terms of the differential political meanings of women's and men's bodies is achieved as that which Pateman has discussed for the Western sexual contract, with one enormous difference: it is accomplished without physical violence – indeed with a strong execration of any violence in association with sex – on one hand, and with the absolute right in principle of the wife to say no strongly encoded in law on the other.

We might, on the other hand, take a different approach entirely: the contraceptive is what separates sex for pleasure from sex for reproduction, and, following Zinger's analysis of Cairo genizah documents, we can see how physical force and economic coercion did very much occur in the marital relationship, as well as how social relationships were women's main form of capital and thus it was very much in women's interest to secure stable relationships that would last into times of potential precarity, such as divorce:
It is also important to understand what costudy meant for women, [a]s [...] the primary form of power for women was their social relationships. As a woman grew older, her supportive kin changed from her father, to her brother, and finally to her children. Thus, cementing the relationship with her children was a woman's most important investment for the future. Therefore, at divorce, it was of paramount importance to retain custody of the children, especially the boys (girls were in any case given over to their mother's custody). To signal women's love for their children as the cause of these compromises not only construes husbands' attempts to shirk their responsibility as natural and transparent but also distorts women's difficult predicament as they had to compromise their immediate economic circumstances for their future prospects.

While both texts give us somewhat contradictory views on our sugya, keeping in mind that both refer to time periods that are not congruent with that of the Talmud, we can nontheless see how the textual system resigning women to the family, excluding them from being actors in the process of halakhah-making, creates a societal system in which the cards are stacked against them one way or another, in which women's consent is at all times a point of compromise.
