I'm not sure how relevant this is to the original question, but the set of real numbers (uncountable) is a different infinity to the set of integers (countable). And the set of real numbers is "dense" in the sense that any two reals have another real between them.

So at least superficially it suggests there may be reasons why implementing the integers with a finite set is more acceptable than implementing the reals with a finite set.
