No, that is w double, what number in the first set became w?

Why not? WHich ones don't?

Nope, it is not finite, but beyound the finite.

Nope, the fact that you admit that you logic breaks the definition of 
the Natural Numbers says you admit your logic can't be used with them.

It may be that you logic just can't handle a mathematics are big and 
powerful as the full definition of the Natural Numbers, but only 
arbirary but finite subsets of them.

You just need to understand your limitations.
