Your argument stems from visible unit fractions
but becomes invalid in the dark domain.
The darkᵂᴹ domain
between 0 and visibleᵂᴹ unit.fractions
is empty.
Each positive point is undercut by
visibleᵂᴹ unit.fractions, and thus
each positive point is not darkᵂᴹ.
⎛ Assume otherwise.
⎜ Assume x > 0 is not.undercut by
⎜ visibleᵂᴹ unit.fractions.
⎜
⎜ β ≥ x > 0 is the least.upper.bound of
⎜ points.not.undercut by visibleᵂᴹ unit.fractions.
⎜
⎜ ½⋅β is not.undercut.
⎜
⎜ 2⋅β is undercut.
⎜ visibleᵂᴹ ⅟k < 2⋅β
⎜ visibleᵂᴹ ¼⋅⅟k < ½⋅β
⎜ ½⋅β is undercut.

⎝ Contradiction.
The problem with your NUF, is that
it is trying to count something from and uncountable end,
one that doesn't actually have an end.

The unit fractions end before zero.
The lower.end of unit fractions
is not a visibleᵂᴹ unit.fraction ⅟k > ⅟(k+1)
is not a darkᵂᴹ unit fraction (not.existing)
is not anything not a unit.fraction.
The lower.end of unit fractions
is not.
