No, it does not "increase", it _jumps_ "at" x = 0.

MEANING:
         NUF(x) = 0 for all x e IR, x <= 0
and
         NUF(x) = aleph_0 for all x e IR, x > 0 .

[NFU(x) = aleph_0] at a point x requires [aleph_0] unit fractions at that point x.

It seems that you have forgotten your OWN definition of NUF, Mückenheim.
No, it does not "require aleph_0 unit fractions at that point x" but aleph_0 unit fractions THAT ARE <= x. (Holy shit!)
Hint: NFU(x) := |{u e {1/n : n e IN} : u <= x}|
