When one applies Stirner’s notion of the spook to one of Society’s most sacred idols, private property, the implications are almost necessarily communist. How many individuals have had their ownness sacrificed and lives ruined by this horrible Moloch? Stirner ridiculed the idea of any right to property (as he ridiculed rights generally), pointing out that property is based on might, or one’s power to get it and keep it. Private property – alien property – is just another spook, because the entire world is the egoist’s property, waiting to be taken. In other words, the communist egoist has for the object of her appropriation the totality of life. Stirner hinted at this with his memorable quotation, “I do not step back shyly from your property, but look at it always as my property, in which I ‘respect’ nothing. Pray do the like with what you call my property!”
This is why I cannot take (much of) leftist philosophy seriously. Animals in nature are territorial (private property) competitive (markets) with some aspects of cooperation (largely non-state charities, NGOs and some state assistance with welfare social safety net programs, public works, ect.). Every attempt to try to completely deconstruct and uproot private property has ended in utter failure and every government that attempted to do so has had to reintroduce markets into their economic system. See USSR with Glasnost and Perestroika, PRC with Deng Xiaoping's "Socialism" with Chinese characteristics, Vietnam with Đổi Mới, Cuba with its recent market reforms and reestablished trade and diplomatic ties with the USA, ect.
