Right-libertarianism (or right-wing libertarianism) refers to libertarian political philosophies that advocate negative rights, natural law, and a radical reversal of the modern welfare state. Right libertarians strongly support private property rights, and defend unequal "distribution" of natural resources and private property. This position is contrasted with that of some versions of left-libertarianism, which maintain that natural resources belong to everyone in some egalitarian manner, either unowned or owned collectively. Right-libertarianism includes anarcho-capitalism and laissez-faire, minarchist liberalism.
The non-aggression principle (NAP) is often described as the foundation of present-day right-libertarian philosophies. It is a moral stance which forbids actions that are inconsistent with capitalist property rights. The principle defines "aggression" and "initiation of force" as violation of these rights. NAP and property rights are closely linked, since what constitutes aggression depends on what libertarians consider to be one's property.
Because the principle redefines aggression in right-libertarian terms, use of the NAP as a justification for right-libertarianism has been criticized as circular reasoning and as rhetorical obfuscation of the coercive nature of libertarian property law enforcement.
