Voluntary celibacy has been around for a long time. Isn't this just a modern version of that?
It's creepy as fuck.
(also, it's seriously racist: I've had Asian female friends my entire life, and none of them are "submissive" or "traditional"... I can't imagine any of them putting up with that shit)
Voluntarily celibacy and, especially, voluntary complete isolation from women have often been sold by organized groups with justifications that incorporate misogyny, so "organized misogyny" and "voluntary celibacy", while distinct, aren't completely independent.
So, I don't think MGOTW is, even to the extent that it combines these things, particularly novel.
I've been to Catholic monasteries in the US, plenty of women around most of them. Either working in the gift shops, volunteering with tasks needed around the monastery (often, the monks are aging and needing more help these days than in earlier eras). A totally cloistered existence is possible, but you're making a major sacrifice. Without a religious motivation I'm having a hard time imagining anyone making that commitment.
As I understand, even the religious groups (including Catholic cloistered religious, which as you note most orders are not) that take isolation to more extreme levels -- of both genders -- tend to do a lot of work to filter out people whose motivations are not religious, so I don't think that a religious motivation is all that essential to choosing such a lifestyle (the typical non-religious motivations may turn out to usually be insufficient to staying with that choice, though...)
