I think you're dreaming about a decentralized or even distributed society. The only reason why you consider this is because you believe that all people are equal and "just want to survive in harmony and be happy". That belief will get you killed in a decentralized society. Man is bad, man does nothing unless he gets something in return - it is the nature of our beast. Someone has to hold people accountable for their actions and without it there is chaos and you end up with a society like Mexico or any other Latin American country.
