 True.

 No, the set of dark numbers is another set without smallest element.

 Correct is: There is no such _definable_ natnumber.

But all Natural Numbers are definable.
You are just creating your "darknesss" to try to hide your stupdity, but it doesn't work.

 There is a general rule not open to further discussion:
When doubling natural numbers we obtain even numbers which have not been doubled.
In potential infinity we obtain more even natural numbers than have been doubled.
In actual infinity we double ℕ and obtain neither ℕ or a subset of ℕ.

Your general rule not open to further discussion is what put you outside the realms of logic.
It is the sharpanel from the explosion to smithereens of your logic system from the contradiction you have put into it.
