In practice, you have the property and property rights that the people around you are willing to concede that you have, and willing to help you defend and uphold. One man cannot stand alone against the world. But enough in confederation can hold hostile hordes at bay indefinitely. Property and property rights are obtained in exchange. You recognize and uphold mine and I’ll do the same for yours. The necessary standard to make property rights durable is mutual insurance, not just “respect mine and I’ll respect yours” but “DEFEND mine and I’ll DEFEND yours.” Practically speaking, you can’t have any rights without positive duties and obligations. Libertarians go wrong when they make a distinction between “positive” and “negative” rights. All rights are positive rights because NO rights can be enjoyed without enforcement and defense; and enforcement and defense must be proactive and have positive costs (although the benefits may be greater.)
Any claims by libertarians that rights are “natural,” “God-given”, “innate,” “inalienable,” “selfevident,” or anything of the sort are moralistic attempts to obtain rights at a discount, without paying the full cost of asserting, maintaining, and defending them, by convincing others to PROVIDE them at their expense. But there can be no such thing, in practice, as a right not to contribute to the maintenance and defense of rights that one demands. Rights, in practice, have to be maintained and defended. Non-contribution to the maintenance and defense of rights is not conducive to their maintenance and defense. Demands for rights while refusing to enter into reciprocal duties and obligations to defend rights is a violation of reciprocity and an act of parasitism, not conducive to long term cooperation. Without cooperation, no rights can successfully be maintained and defended.
