There is no precision, no "genau" with ℵo.

You cannot think so far? What a pity.

Not for the first ℵo points and their intervals required that the number
of unit fractions can grow to ℵo.

You cannot draw the conclusion: If X unit fractions occupy X points, then
there cannot exist more than X unit fractions at the first X points.
Ob alle Mathematiker zu blöde sind, um das zu verstehen?
