The nonnegative integers may well be only cardinalities, which will not be simultaneously real numbers in any context where most real numbers are nonsensical, such as in counting. One cannot have pi people or any other nonnatural number of people, other than 0 if your notion of N excludes 0. So in counting contexts, the results of a count will always be counting numbers, i.e., 0's or naturals, and will not be= integers, nor rationals, nor reals or complexes, nor quaternions, nor anything else.
