Natural law is a whole lot simpler system to live by, not only do you have a abundance of philanthropist, but an exchanging of goods and services without the use of money. At one time there was a concept called barter banking, but now it s morphed into something called time banking. I spend an hour fixing some ones car, we agree on a hour worked, that gets put into the time bank and then later I spend that where someone cooks me a meal, also in this concept it does not have to be a direct exchange either.
My family takes part in a co-op or 2, plus we also participate in a community meal potluck style and there is always more then enough to eat for everyone at that time. The concepts are no more just a idea for us, we actually are living them out and encourage others to do the same.
