When you look at a set of consecutive whole numbers starting from 1, if you
know the set size, you know the last element, and if you know the last element
you know the set size. However, for the set as a whole, you claim the set isze
is infinite, and all elements are finite, which is a contradiction. For any
range of values, finite or infinite, the largest element and the set size are
the same.
