You cannot save the world by running away from it.
Yet, it seems the western monks did contribute to saving Western culture, as Eastern monks did to their cultures (disclosure: I'm not well educated on Orthodox history).
The dedication to prayer, contemplation, and the pursuit of holiness - it's all about forming a spiritual barrier against the forces of moral decay outside.
I may seem to be belaboring the point, but I think your distinction is upside-down. The dedication to prayer, contemplation, and pursuit of holiness in not put a barrier between oneself and the world, but the barrier is to provide an environment for one to pursue a life of prayer, contemplation, and pursuit of holiness.
If the monastery was about the former, I'd agree it's a stupid thing, perhaps I'd even call it anti-Christian. The latter, however, is of enormous value.
I'd argue that the monk doesn't enter the monastery to save the world, but to save his soul--that holiness then has a mystical effect on the world because we are inter-connected on some level.
