Freedom is the societal condition that exists when all interactions are voluntary. This means no coercion, ever, for any reason.
Coercion is the initiation of physical force or fraud.
Physical force used in defense against the initiation of physical force is not coercion. The threat of physical force in the employ of contract enforcement is also not coercion. The threat of physical force, voluntarily subscribed to, is the administration of physical force. The political state practices coercion. We have the political state, we need government.
