This is interesting. I see youth trying to create online villages in the place of real world communities, but they do not work well (and can be harmful with bullying etc) because we don't see the overall complexity and nuances of others very well online, but tend to focus on one single aspect of others, not the full human beings.
Tribalism of a very simplistic type is rife in social media, and a person can be tossed out for one single wrongspeak statement. In real world 'villages' John next door is an ass about politics, but he shovels the snow of all the older people without being asked and without expecting pay. Aunt Ellie is nosy and a gossip and vain, but when someone is ill or in great trouble it is she who comes in to clean and care and connect the person to sources of help. And so on.
Earlier recent generations of feminists wrote a lot about the isolation of women in nuclear families, stranded in some suburban area with small children, no transportation and no help, and compared that to the older wider kin -based arrangements. Harrington's arguments wouldn't help this problem at all, and neither would they have any effect on the way the arrangements she supports would perpetuate the lifetime earnings differences between men and women.
Feminists differ in how same or different they see the two sexes, how much overlap there might be, whether men could do more child-rearing and make more career sacrifices for that, but ultimately feminism must tackle the fact that the unpaid work by women does leave them with lower lifetime incomes and fewer alternatives in divorce and so with less negotiating power inside marriages.
And some type of village arrangements are in my view necessary for both this (that women could also thrive as human beings) as well as the psychological well-being of all.
