"Capitalism" is the economics of free choice. As Milton Friedman used to say, "I believe in capitalist acts between consenting adults." If I grow apples and you want to buy apples, we shouldn't need a government planner, or a government license, to do business. That's capitalism.
But as soon as you use the word “buy” you move right back into the substance created from nothing.
Now . . . you can say “trade” and have it mean something, but nowadays even trade is measured in dollars, which were created from nothing.
Visualize scarcity. That is where the education arrives. You have food. Someone else has a billion dollars. There is no other food anywhere else. He wants to buy your food.
Clearly, you refuse to sell. Scarcity exposes all the silliness of defining morality with money.
