Consider once again the haecceitistic possibility according to which you do not exist and a different individual, Double, instantiates all of your actual qualitative properties. A natural way to describe this possibility is as one where the distribution of qualitative properties is just as it actually is, but where non-qualitative properties are distributed differently. In particular, this alleged possibility is one according to which your haecceity goes uninstantiated and the haecceity of a non-actual individual, Double, is instantiated in its place.
