I would only go as far to say that the description of the universe
must be discrete, not that the universe so described is discrete. For
example, the set of rational number admits a discrete description of
all its members, yet is not a discrete space (between any two rational
number lie an infinity of other rationals).

Why should the description of the universe be discrete? Because we're
universal turing machines (but not just UTMs mind - let's not get
computationally carried away). I have some private speculations with
some others about the possible existence of super beings who might
transend the UTM capability. Perhaps the ability to compute a
countably infinite number of computaional steps in finite time changes
fundamentally the form of the universe's description.
