Hint@Mückenheim:

No, "ℵo unit fractions" don't "require a minimum length d" - IN THE 
FOLLOWING SENSE:

For each and every d e IR, d > 0, there are ℵo unit fractions which are 
in (0, d).

OF COURSE, if we consider a (non empty) set of "given" unit fractions S, 
then the unit fractions in S "require" an interval of length d = max S - 
inf S.
