A finite initial segment of |N is not a path in the unary tree |N.

And neither |N as a unary tree nor any Complete Infinite Binary Tree
has any finite paths.

"A Complete Infinite Binary Tree cannot be built with only
finite paths, as none of its paths can be finite."

Means the same as

"A Complete Infinite Binary Tree cannot be built HAVING only
finite paths, as none of its paths can be finite."

WM has this CRAZY notion that a path in a COMPLETE INFINITE BINARY TREE
can refer to certain finite sets of nodes.

And no one is claiming any infinite naturals, only infinitely many
finite naturals.
