The theory that predicts there is a shortest measured interval assumes a continuum.  There's no logical contradiction is this. But physicists tend to have a positivist attitude and think that a theory that assumes things, like arbitrarily short intervals, might be better expressed and simpler in some way that avoids those assumptions.  This attitude does not assume the mathematics itself is the reality, but only a description of reality; so there can be different descriptions of the same reality.
