SBZ(x) starts with 0 at 0 and increases,

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?
 How can ½⋅β

Visible unit fractions have the lower bound 0.
Dark unit fractions have a smallest element. No smaller unit fractions is existing because no larger natnumber is existing.
