> They support "radical individualism" (anarchy) and "free market absolutism" (hierarchy). This is a blatant contradiction no matter how you talk your way out of it.

Not quite, they support property rights, which is something that social anarchists implicitly accept as well, they just have a different conception of how that would work. To a right anarchist or libertarian, "Free market absolution" is not an ideology or a goal, it's just the result of private property rights + freedom of association.

Most right-wing libertarians and right-wing anarchists (allow me this even if you disagree with the phrase) are against copyright because it's nonsensical in their conception of what property is and how property rights work. I would assume that left leaning libertarians and social anarchists would also similarly agree that copyright is nonsense but I'm not so sure - the time I spent in those communities have me wondering if they even hate authority and hierarchy, or if they simply desire their own forms of it. Many indeed defend copyright.
