The moral promise of a free society involves the boundaries of private property. When property is protected, people can keep the fruits of their labor and investment, and not have them plundered by others. People can own land, for example, and this land can be used as the owners see fit.
Private property allows wide latitude for experimentation.
Property holders can form communities with their own internal cultures. Just as business can conduct its own affairs, people can separate themselves out entirely from the rest of society if they so desire. They need only respect the rights of others to do the same. It's the nature of private property and a free society that it allows room for diversity of work, modes of production, and ways of life. That's how Mr. Jefferson wanted it, and that's what the authors of the Constitution promised.
