The reason is potential infinity. But dark unit fractions are assumed to be actually infinite.
 
It starts from 0.
 If ⅟ℕᵈᵉᶠ starts,
⅟ℕᵈᵉᶠ starts from min.⅟ℕᵈᵉᶠ
 No min.⅟ℕᵈᵉᶠ exists.
⅟ℕᵈᵉᶠ does not start.
 Because 0 is glb.⅟ℕᵈᵉᶠ not.in ⅟ℕᵈᵉᶠ
All that is correct for definable unit fractions.
But NUF(x) starts from 0 and cannot avoid to take the values 1, 2, 3, ... .
