I agree: properties in the first place are projections of classes
(the property of being red is just a reification of the class of red
things), so reducing properties back to classes doesn't help.

That's what's sticky. There are no unicorns, and there are no
purple (by nature) rhinos, but there is only one null set.
Likewise, having a heart does not equal having a kidney, but the set of
heart-havers turns out to be the same as the set of kidney-havers.

Kripke nailed this one in "Naming and Necessity", which should definitely
form part of remedial reading. Xworld identification is a non-issue, because
it presumes an incorrect (and in fact meaningless) model of possible worlds.
We don't scan possible worlds as with a telescope, we create them by
talking about pivotal individuals (you in this case).
