A nonempty set without a first element is not a set of only finite

Proof: If you double all your finite ordinals you obtain only finite
ordinals again,
although the same infinity,
although the covered interval is twice as large as the
original interval covered by "all" your finite ordinals.
Nah. There are countably many (Aleph_0) even numbers. Blah blah
consecutive. If 2n>n, then also 2(n+1)>n+1.
