Yeah my take away was that the quantum thing was a bit of a red herring, and that the real distinction being made was between classes and instances.
I’ve written a post on this already, but its explicitly mentioned that ‘quantum events’ are not actual entities because they are particles, and actual entities are a metaphysical category. The definition of a quantum event is misguided but it seems the point was just that actual entities as a class refer to instances. In otherwords there’s a hierarchy of abstraction, and actual entities are a generic referent rather than the signified objects (the actual ‘actual entities’) that they encapsulate.
Hope these 2c are helpful
