Hint: If u and u' are two different unit fractions, x := (u +  u')/2 is a real number between u and u'.

> But not for the ℵ₀ unit fractions which are missing any x between them?

No two (different) unit fractions are without (uncountably many) real numbers between them, you silly idiot.

Hint: If u and u' are two different unit fractions, the interval I := (min(u,  u'), max(u, u')) is a nonempty set of real numbers such that for all x e IR: x e I <-> min(u,  u') < x < max(u, u').
