We cannot name dark numbers as individuals.
 We needn't. The axioms of natural numbers ensure that every natural number
has a successor,
The set, i.e. all numbers together, has no successor. That is a necessary condition for using all with no exception. That must happen according to
∀k ∈ ℕ : ∩{E(1), E(2), ..., E(k+1)} = ∩{E(1), E(2), ..., E(k)} \ {k}.

If that is not possible then there are no
natural numbers.
That is not possible for an actually infinite set. It is only possible for numbers coming into being.
