Guardians are necessary for children and abnormal adults, because they cannot make responsible choices for themselves.

Libertarians argue that no normal adult has the right to impose choices on other normal adults, except in abnormal circumstances, such as when one person finds another unconscious and administers medical assistance or calls an ambulance.

But there is no obvious reason for holding that some normal adults are entitled to make choices for other normal adults, as paternalists of both left and right believe.

Equality of rights means that some people cannot simply impose obligations on others, for the moral agency and rights of those others would then be violated.

The first census in 1790 asked just six questions: the name of the head of the household, the number of free white males older than 16, the number of free white males younger than 16, the number of free white females, the number of other free persons, and the number of slaves.

The reason the government sells the census as your ticket to getting goodies - rather than as your civic duty - is that distributing goodies is now all the government does.

Libertarians typically argue that particular obligations, at least under normal circumstances, must be created by consent; they cannot be unilaterally imposed by others.
