I don't understand your rational. My rational is that people obey ownership laws because the government uses its monopoly on legitimate violence to enforce ownership laws; that even the threat of enforcement is enough to compel obedience 99.9% of the time. Sure, enforcement doesn't explain how the powerful decide which laws will be enforced; the powerful could easily choose to enforce laws that are based upon a conceptual framework like ownership that in the end is nothing more than a "hallucination" as you point out. But when the masses obey that law, they are not obeying the hallucination that the powerful chose to turn into law; the masses are obeying because of the threat of violence, which is very real.
