No. NUF(x) counts the unit fractions between 0 and x. Between 0 and 0
there is no unit fraction. NUF(0) = 0.

It cannot increase to 2 or more before having accepted 1.

NUFᵈᵉᶠ(x) cannot increase to 2 without having already been ≥ 2

Impossible. NUF(0) = 0. There is a first increase in linear order.

It cannot increase to ℵo without having accepted 1, 2, 3, ...

x > 0  ⇒
0 < ... < ⅟⌊4+⅟x⌋ < ⅟⌊3+⅟x⌋ < ⅟⌊2+⅟x⌋ < ⅟⌊1+⅟x⌋ < x

0 is smaller than all that. Therefore there is no increase at 0.
x is larger than all that. Therefore your x is not the least one
posiible.
