Do you mean with regard to contemporary feminism? I'd like to read some more contemporary feminism. I'm guessing a lot of it is on-line. So I hope someone comes along with some answers.
I think if you looked back to earlier feminism, you'd find this topic discussed. I'll bet you would find some good articles discussing French feminism, written by left-wing affiliated Anglo-American feminist critics, suggesting that some French feminism is ideologically descended from libertarian critiques of the collectivist Left. And articles arguing just the opposite. In the interstices of these, I reckon you could discern the outlines of a feminism premissed on something other than the ideal of an autonomous agent.
Mind you, it might get quite interesting because a lot of those French feminists argued that they strategically utilised libertarianism in order to undermine the ideal of the autonomous agent (a patriarchal construct), thus putting two parts of your notion (libertarian = autonomous agent, in possession of free will) in opposition, and putting your supposed opposing ideas (collectivist subject; made up of forces beyond free-will versus bounded subject; with agency; in possession of free-will; libertarian) in a (loose) tandem: (the subject of feminism is essentially collective, in that s/he is intimately structured by socialisation, multiple, and riven by contrary desires - both conscious and unconscious. The idea of the individual agent is male fantasy of the Enlightenment.
I also think that a lot of Left feminists would quite unconsciously have assumed that women were a collective class.
I wonder if what you are looking isn't that widespread (ie. there is not a lot of it) - other than in palimpsestic or fragmentary form because feminism often has a very pragmatic quality. Perhaps that is because it has no ur-text? Maybe it's because it is always "feminisms" so there just isn't quite the impulse to write manifestoes and examine premisses?
I don't know.
I must admit, I'm not sure I agree with your premiss about libertarianism. I loathe libertarianism. My feminism is pretty anti-libertarianism. A lot of my friends have a strong critique of it (well, OK, two of them!! Though one is dead
. Though I haven't discussed the issue much over the last 10 years.). Which brings us to the thorny question of what is feminism? Whose feminism is "libertarian"?
For example: If a form of feminism has been selected to be preserved through history and is taken to be the dominant representative of feminism, and if this form of feminism is, say, libertarian in its premisses, is it possible still to be authentically feminist, or to be espousing an authentically feminist discourse, if your discourse is anti-libertarian?
