The universe is the container of all things.

Since abstractions are the result of humanity's metaphysical relationship to such a universe, that means even abstractions must therefore be internal.

Especially since, on the basis of your own epistemological argument, you do not think the universe has any externalities.

Since the universe lacks externalities, and abstractions are therefore internal to the universe, then that must also mean that whatever the Platonic essence of what is ordinary is also without externality.

Since it is internal to the universe, the universe must therefore by the same token be external to such an abstraction.

Ipso Facto: The universe is extraordinary.

I've lived my whole life in the universe and I don't appreciate it when people try to talk down to me about it.
