Sam quoted Creating Cohousing by Kathryn McCamant
People who choose cohousing do not seek the isolation of ideological purity, no matter how liberal or conservative its orientation. Rather, they seek a sense of place fostered by regular dinners together; common space with cars parked at the periphery; consumer goods (lawn mowers, washers and dryers, and the like) and property shared in common or owned individually as each makes sense, in an effort to create a highs functioning neighborhood where people know and care about each other.
— Creating Cohousing by Kathryn McCamant, Charles Durrett (Page 71)
I never fully understood the difference between co-housing and an intentional community before, but I think the ideological angle sums it up well.
