Questions: How will children be educated? How will people get health care? How will business fluctuations be prevented or moderated? How will people get personal security? How will people receive income when they can no longer work? How will the society’s distressed and disabled receive support and care?
Statist answer: Only by employing threats and actual use of the government’s force and violence. Pass laws, and send out the cops to enforce them.
Libertarian answer: By leaving people alone to deal with these matters through private, cooperative measures voluntarily arranged. Remove government obstructions and penalties, and get out of the way while people arrange their lives in the great variety of ways that suit their personal preferences without resort to force and violence.
