ok by 'any' here you mean all, not exists one string.
but this is trivial, just order S and add one more element.

its a strange way to define a new element.

N <-bijection-> S <-bijection-> X <-element of X not in S

it has to be longer than the *largest* string in S
S is almost identical to X

Noone can follow the proof without.

Haven't you just proven all finite lists are incomplete?
