The liberty of free riders: the minimum coverage provision, Mill's "harm principle," and American social morality.

A direct requirement for most Americans to purchase any product or service .... certainly is an encroachment on individual liberty, but it is no more so than a command that restaurants or hotels are obliged to serve all customers regardless of race, that gravely ill individuals cannot use a substance their doctors described as the only effective palliative for excruciating pain, or that a farmer cannot grow enough wheat to support his own family. The right to be free from federal regulation is not absolute, and yields to the imperative that Congress be free to forge national solutions to national problems, no matter how local--or seemingly passive--their individual origins.
