The term appears to have been coined by Edward Cain in 1963: Since their use of the word "liberty" refers almost exclusively to property, it would be helpful if we had some other word, such as "propertarian," to describe them. [...] Novelist Ayn Rand is not a conservative at all but claims to be very relevant. She is a radical capitalist, and is the closest to what I mean by a propertarian.
Marcus Cunliffe defined propertarianism in his 1973 lectures as "characteristic values of American history" in regard to property. Philosopher
Robert Nozick formalized Locke's approach in his book "Anarchy, State, and Utopia" with the
Entitlement Theory of Justice, specifying criteria for just original acquisition, just transfer, and rectification.
David Boaz writes that the "propertarian approach to privacy", both morally and legally, has ensured Americans' privacy rights. Markus Verhaegh states that Rothbardian
anarcho-capitalism advocates the neo-
Lockean idea that property only legitimately originates from labor and may then only legitimately change hands by trade or gift.
Brian Doherty describes
Murray Rothbard's form of
libertarianism as propertarian because he "reduced all human rights to rights of property, beginning with the natural right of self-ownership".
L. Neil Smith describes propertarianism as a positive libertarian philosophy in his
alternate history novels
The Probability Broach (1980) and
The American Zone (2002). == Alternative meanings ==
