Private property includes land and the machinery used in order to exploit labour within capitalism; I don't believe that those who hold the 'right' to this property do so legitimately, as they can only back up their claim via (i) the state (which has not been shown to be legitimate) and (ii) title transferred from a previous owner. The latter is a result of violent defence of property that someone claimed as his own long ago; again, the legitimacy of this has yet to be shown. I regard the following as illegitimate: (i) private property used in order to create profit via exploitation of labour in exchange for wages, and (ii) private property which is neither used (i.e occupied) nor laboured upon. My aim is not to have property shared amongst people, but rather to abolish the concept altogether, along with all concepts of morality and justice.
