This is interesting, and I would have been thinking still some intentional community might be needed, if there was such a one approaching this. But community building is needed, for the sake of lasting ways for people to be living. And people need to be compatible to be together for this, we should not have difficulties with our beliefs among others for that.
I know of natural farming ways I would like to have some use of for growing some things in simplicity. And as I write, I see use in making paper, and want to learn of natural inks. There can still be written things for others that this way may still spread, when internet connections, and even phones, might not be used anymore, as those are not a part of such simplicity.
