The list is endless, these are the ones I know: Amana, Onieda, dozens of Shaker communes, the Rappites, Brook Farm, Ephrata, New Harmony, House of David, Point Loma, Temple Home, Zoarites, Moaravians, Bethel Colony, Aurora, Kaweah, Joyful, Alturia, Winters Island, Koreshan Unity, Kastania (for you who live up in Petaluma) ....
After a century of failure with people voluntarily living communally, the obvious solution in the 20th Century was forced communal living with death as the punishment for trying to leave.
Can most people draw a simple conclusion from two centuries of failure? Most people can't.
