OK. How do I (or any of the "Lemming humans" from the intro) know if something is voluntary without just trying it out?
Person A wants an apple, but doesn't have one. Person B has an apple.
Person A takes the apple from person B. I agree that without some kind of communication or 'trade', that would might be naughty.
But how does person A know that they should 'negotiate' with person B over the terms and conditions for getting the apple?
If we take the "apple transaction" as a simulation of Capitalism, there seem to be some special rules for the nature of the interaction. Where do those rules come from? And how do people learn what those rules are?
A expresses preference for the apple from B and suggests a form of consideration (money, other product, sexual favors, getting rid of debt, altruistic feeling, friendship, etc.)
B accepts or denies
Accept and trade occurs.
Deny and suggest alternative or trade doesn't go through and A and B separate having not traded.
A accepts or denies alternative
so on..
They know they should negotiate because of voluntary interaction from others. If A beats up B, then C, D, and E will want nothing to do with A. Thus A can't get all the products and services he may want and lives a less fulfilling life that requires him to provide for himself more as the others do not want to interact with him.
People learn from personal experience and the collective wisdom of all who came before. It is the idea of spontaneous order. At the college I went to, paths had been made in the snow from many feet walking between paths. No one planned the paths. People can walk through the snow if they think it will be a better path from them, or they can take the one that everyone else took where the snow is packed down. The result is 99% of people take the same paths and they are the most efficient paths for the most people.
Those who go their own way have a harder path to travel, but may need to move really quick to get to class on time or something.
Those who build their own path, charge a toll for use and beat up anyone who takes another path gets no friends, realizes his costs exceed his profit, and quickly finds another way to get things done.
