Your claim boils down to a claim that there exists some n in the Natural Numbers that doesn't have a next number, and thus your set of Natural Numbers is NOT the infinite set they are defined to be, but only some finite initial subsequence of the real numbers, and your logic never had a correct idea of infinity, Sorry, you are just proving that you werte NEVER talking about the actual set of Natural Numbers, just some made up finite subset of them, and your "dark" numbers are just the actual existing Natural Numbers that you have refused to look at because you ran out of ways to count to them.
