Such a number does not exist because every set of reals which has a
lower bound has a real number as its infimum.
(Of course, such arithmetic structures can be defined, but it's a lot
more involved than that.)

In this context, it does not make much sense to allow only
non-negative integers for z, so your interpretation is anything but
natural and as good as any other total odering.
