Friedman is saying that free markets are simply people making voluntary choices with their own lives and resources. When someone argues against that, they often don’t trust people to choose well. They would rather have a committee or a law decide for everyone, which is another way of saying they prefer control over freedom.

Belief in freedom means accepting that people will try, fail, learn, and improve—and that this messy process creates progress. If we respect each person’s right to choose, trade, and build, we unleash creativity and responsibility. Doubting the market is often just doubting your neighbor’s ability to live as a free adult.
