Right, but is this not just a variation of some mathematicians' argument?  That 
is, are you not assuming by your own concept of "interesting number" that an 
"interesting number" has to have a certain "constructive" characteristic? (Mind 
you, I am just playing the devil's advocate.)

Sure, but the problem is that there's no one canonical well-ordering
so you can get any smallest non-interesting number depending on the
choice of the ordering.  In contrast, natural numbers have a canonical
ordering, and integers or rationals have at least one interesting
canonical ordering as well.
