Yes I agree everything takes time! Time is something very few have. They have tent cities everywhere and not everyone wants to take over someone’s land plus live onto of each other. You don’t get to choose who you live next to let alone the values. Yes kids are involved but none under the age of 13. The last guy who answered told me to Bing "intentional communities" while up front might be an answer but we don’t want some ritual guru experience. We are not trying to create a cult just provide stable housing in this most honest reliable way.
There are people who have land that just sit there doing nothing with it. Some have even had it perk tested. Again everything takes time but if people start wanting to help one another and stop trying to just look out for themselves. When we die we can’t anything with us.
Going back to living as our ancestors did would not harm anyone one of us. They did it and lived just fine. As for food supply the smart thing is we have food storage saved up and we are actually pretty resourceful and knowledgeable about building, electrical and plumbing. We have also been doing research on how to make water safe for drinking, cooking etc and providing necessary electrical needs without running off a power company. We know you must look before you leap.
