The single greatest benefit that capitalism provides is that it enables human choice. Capitalism establishes a social contract that makes it possible for individuals to exercise their franchise and free agency. It gives people the ability to be secure in themselves and their possessions and, having provided security, it enables people to assume risk that they were previously unwilling to assume. It creates the necessary conditions for people to escape poverty and create wealth for themselves and for others.
The whole summary of the excerpt is providing individuals with freedom of choice which is emphasized by both Adam Smith and Butters on capitalism
