You need to think more outside the box and go much further back in history for examples of the kind of reciprocity and redistribution that society was based upon. This idea that we naturally barter for goods took hold in the 19th century during the destruction of a very different way of life. We can and must do better.
What is the organization of this society? I think its fine to criticize capitalism, it has its flaws yes, but you have to fully consider and acknowledge its strengths, which socialists/marxists rarely do.
You said you want agriculture to be publicly owned, but you don't realize that throughout history this has caused terrible famines killing millions & sometimes tens of millions of people (ie: USSR, China, North Korea), and the reason is because governments tend to often be significantly less efficient & productive than the invisible hand of a mostly free and competitive market and involves the freedom of millions of voluntary transactions instead of politicians & bureaucrats who think they can make better decisions for people than they can themselves. Ontario's hydro system is just one evidence of that. In a mildly regulated free market of competitive companies, Ontario Hydro would have gone bankrupt long ago because consumers would have found a cheaper competitor. If the food system were mismanaged like the hydro system people would be paying out the nose for their food.
Nobody has figured out a better way to manage an economy than letting people figure it out themselves. If you can figure out a better & more ethical way than a mildly regulated but mostly privatized capitalist economy I'm all ears.
