The premise is Red Pill 101, so it's nothing new. This is the central tenet of the 'Women in Love' article in the sidebar.

But to say MGTOW is the best prescription? This is very subjective. If it works for you, sure why not. But it may not work, or even fail miserably, for others.

There are MGTOWs who believe sexual intimacy is an impossible dream given the limitations of woman. It's a more subtle form of delusion. The results are not immediate. The results only become apparent many years later.

The whole point of Game is to minimize the bad and maximize the good in your dealings with women. There's an extremist faction of MGTOWs who reject the possibility of meaningful sexual intimacy -- categorically. It's impossible only if you want a woman to love you like you love yourself. In reality the adoration of a woman for a man who tingles her can be a very spiritually (and physically) fulfilling experience for the man, even if it's transitory and unreliable.

Look at Mark Minter for example. He was a hardline MGTOW who swore up and down that he would NEVER EVER commit to a woman, until he gave up and married a post-Wall woman in his fifties, for lack of options, and mostly because he felt alone and unhappy.

The danger of chasing self-sufficiency for the sake of self-sufficiency is that you never gain the exposure, the experience required to Game younger, attractive women. It is putting all your eggs into one basket -- 'I can be happy alone. I can be happy alone! I can be happy alone!'

What if you're horny and lonely in your late forties -- lonely to the depths of your soul and spirit -- and you want a sexual relationship with a young hottie but you don't know how to get it? Then guess what, you are miserable. Not happy. Miserable.

Going into Monk Mode is well and good when you're in your late twenties and early thirties, but to choose that permanently? That's a very subjective choice.

For some omegas who are just scraping by in life, unable to attract quality women due to health/financial issues, etc, perhaps that is the wisest option. But for deltas and betas in the prime of their life? It is a self-limiting strategy.

Game is a skill that requires enough consistent practice at the beginning such that you master the basics. Then you can afford to slack and enjoy other things in life, occasionally bringing a pretty girl into it. So the first few years of simply going out and talking to girls is very important for young men because there's a huge return on the investment. Building a strong foundation in this area also improves your self-confidence in other areas. (http://heartiste.wordpress.com/2012/04/13/the-numbers-game-fallacy/)

Nobody is saying you need to do LTRs and marriage. Marriage is blue pill nonsense. Why not spin plates? Why not go to a country where the women have not gone feral yet? There has to be a better answer for men than, 'Women are fundamentally evil. We must avoid them completely. Full stop.' This is the philosophy of a doomed species that knows its time is running out.

EDIT:

As /u/Class-Punk pointed out, I was being rather misleading and arguing against a strawman by neglecting to mention that there are many levels of MGTOW. Sorry about that.

Level 1, 'Situational Awareness', overlaps a lot with red pill ideas.

Then there's Level 2, 'Rejection of long-term relationships with women'. Self-explanatory.

Monk Mode is superficially similar to Level 3, 'Rejection of short-term relationships with women', but it's not the same. Monk Mode is about delayed gratification -- avoiding women to work on your SMV -- not "rejection".

Hope this makes things clearer.
