Hello Lanolin;
I would assume this book is fiction.
I'm sorry, Lanolin, I don't mean to rain on your thread but I'm not in favor of communes. It reminds me of the history such as the Waco Siege, a Christian sect called the Branch Davidians in 1993 and the People's Temple, another Christian sect led by Jimmy Jones in 1978. Both ended tragically.
My thoughts on what you shared; In "real life" communes are most people who have resigned from co-existing with society. Some justify the woes of the world so they drop out in search for communal life. Problem is most of the commune or tribal leaders don't put together a proper plan for the people who will join.
Biblically speaking, men have a role to honor God's creation of marriage, not to share women and have babies as they please, making it a communal law or rule. Other men love the utopia feel of perfect living within the confines of nature. But when they realize it's tough to kill for food or defend the tribe from beastly animals, they soon lose that nirvana, pack up and surrender back into human society.
Women end up doing the cooking which may include chopping wood, cleaning and childcare. They become sexual objects to the men or the leaders with the attitude that this is ok for communal living.
People in communes still have to deal with communal health such as care of their bodies, care for their teeth, sanitation and prevention from diseases, viruses, etc...
Over time, communal living becomes unbalanced. The communal leaders don't have a proper structure proven and end up becoming a sect. This is why most communes don't succeed. Most communes don't succeed because God's hand isn't in it.
I can read a book on communal living or watch a documentary. But in the end they just don't work.
God bless you, Lanolin.
Bob
