I think that this is one of those strange artifacts from a modern time, perhaps not so much a post-modern one. People are (justifiably) critiquing it because yes, there really isn't as much divide as sometimes we are sometimes taught — I'm guessing it's a holdover from a different type of political self-articulation wherein there is a strict divide between the politic and the populace, and the idea that someone exists qua the individual self-sustained.
Reading a lot of the self-articulation philosophy from 19th c Russia (Westernizer vs Slavophile debate) helps me with this because the personal/political divide was a surprisingly large point of the discourse. Rather interestingly, it's not so much critiqued from the 'socialist' perspective since Belinsky et al probably thought that the personal needed to be liberated even though they were certainly more than aware of the dependent nature... but if I remember correctly, Khomyakov has a pretty scathing critique of the personal/political since he views it as an intrusion from secular/Western thought and it interferes pretty severely with the sobornost' model he's committed to. I've been coming around to sobornost' lately (at least theologically — esp in the vein of Kireevsky, which I might talk about at another time) and I think Khomyakov's critique holds reasonably true: the personal/political makes no sense when personal actions interfere with the political, and, in Khomyakov's model, the religious public. I think a lot of Khomyakov's critique can be sourced within his commitment to the archaic social/economic model he benefited off of, but I don't think it's worth dismissing him outright.
