Private property, properly defined, means that an object or a state of affairs is valued as a good and owned by someone who decides upon its use in a sovereign way and with respect to all dimensions of it (usus, usus fructus, abusus). The uncritically transposition of moral conceptions, such as distributive justice and voluntariness, into the political sphere helps modern socialist reasoning in combining capitalist principles with collectivist ones and thus undermining private property.
