Full Idea

It is easier to generalize von Neumann's finite ordinals into the transfinite. All Zermelo's nonzero finite ordinals are singletons, but if ω were a singleton it is hard to see how if could fail to be the successor of its member and so not a limit.

Gist of Idea

Von Neumann's ordinals generalise into the transfinite better, because Zermelo's ω is a singleton
