That claim has been disproved.
You (WM) are confused about what that claim is.
Something that is before each and every x > 0
sits at zero or at the negative real line.
⎛ That claim is not that
⎜ one unit fraction or ℵ₀.many unit.fractions
⎝ sit at zero or at the negative real line.
Each ℵ₀.sequenceᴶᴮ matches each ℵ₀.sequenceᴶᴮ
element.to.element.
Each ℵ₀.sequenceᴶᴮ holds ℵ₀.many.
For ℵ₀.sequenceᴶᴮ A ordered by '<'
⎛ for each nonempty B ⊆ A: firstᑉ.B ∈ B
⎜ for each j ∈ A: first.afterᑉ.j ∈ A\{firstᑉ.A}
⎝ for each k ∈ A\{firstᑉ.A}: last.beforeᑉ.k ∈ A
For each real x > 0
the unit fractions ⅟ℕ∩(0,x] ordered by '>'
is an ℵ₀.sequenceᴶᴮ and holds ℵ₀.many
...because...
For each nonempty B ⊆ ⅟ℕ∩(0,x]
⅟B = {⅟u: u ∈ B} is a nonempty subset of ℕ
exists min.⅟B ∈ ⅟B ⊆ ℕ
⅟(min.⅟B) = max.B ∈ B
max.(⅟ℕ∩(0,x]) = ⅟⌈⅟x⌉
For each u ∈ ⅟ℕ∩(0,x]: ⅟(1+⅟u) ∈ ⅟ℕ∩(0,x]\{⅟⌈⅟x⌉}
For each v ∈ ⅟ℕ∩(0,x]\{⅟⌈⅟x⌉}: ⅟(-1+⅟v) ∈ ⅟ℕ∩(0,x]
Therefore,
for each real x > 0
the unit fractions ⅟ℕ∩(0,x] ordered by '>'
is an ℵ₀.sequenceᴶᴮ and holds ℵ₀.many
and NUF(x) = |⅟ℕ∩(0,x]| = ℵ₀
∀ᴿx>0: NUF(x) = ℵ₀
