 SBZ(x) starts with 0 at 0 and increases, but at no point x it increases by more than 1 because of
∀n ∈ ℕ: 1/n - 1/(n+1) > 0. Therefore there is a smallest unit fractions and vice versa a greatest natnumber.
What can't you understand?

But there is no point (>0) where it has a finite value,

You can't see it and you are unable to derive it from mathematics. But blindness is not an argument.
