Because all unit fractions are undercut by some x. The x undercutting the last unit fractions (you said that none remains because the set is empty, therefore all must be gone) do not satisfy your following claim:No, that is THE question.The set of unit fractions smaller than all x is empty.
However, the set of UFs smaller than one arbitrary x is infinite.Regards, WM
