Nope, which just shows your too small mind.
The alternative is that the unit fractions keep getting closer and closer without limit.

 The natural numbers n belonging to the first infinitely many unit fractions 1/n, i.e. there where NUF(x) increases at one point from 0 to infinity, cannot be distinguished in your opinion. Thus they are unreachable.

But no "n" is the last of that infininte set.

 

By that and by its well.order,
there is no unreachable natural number.

 If ω-1 could be seen. But it cannot.

No, it just doesn't exist in the set, just like 0-1 doesn't exist in the Natural Numbers (only an extension of them).
