On that basis, no set can exist.
But as set theories do exist, perhaps removing all the elements from a
set does not mean that the original set did not exist.

True but irrelevant.
To say that some subsets of one set are subsets of another does not make
all of them subsets of the other, and A is neither a subset nor a member
of B.

It is not similar enough

WM has not proved it yet!
At least not with any arguemnt valid outside of his hideaway from logic,
