[3]Marcus Cunliffe defined propertarianism in his 1973 lectures as "characteristic values of American history" in regard to property.
[4][5][6][7] 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.
[10] L. Neil Smith describes propertarianism as a positive libertarian philosophy in his alternate history novels The Probability Broach (1980) and The American Zone (2002).
The propertarians, in effect – acolytes of Ayn Rand, the earth mother of greed, egotism, and the virtues of property – have appropriated expressions and traditions that should have been expressed by radicals but were willfully neglected because of the lure of European and Asian traditions of socialism, socialisms that are now entering into decline in the very countries in which they originated.
And, needless to say, if we do not accept the right-libertarians’ view of what constitutes "legitimate" "rights," then their claim to be defenders of liberty is weak.
