I should hope so.

If "there are as many *finite* paths as nodes", then what do the infinite paths
consist of? Don't they have nodes as well? Are there infinite paths, if all the
nodes are used up in the finite paths?

Good. I got called into duty yesterday before I could finish it but it's posted
now. And, no leaf nodes or lack thereof for Virgil to chew on, redundantly
reiterating the same repetitive statement verbatim over and over.

Nope, not. It requires two nodes to make a new path, anyway. One creates a new
path when one adds a second child to a node. refer to my demonstration of node
insertion.

Cantorians pretend they know what they are talking about, but always seem to
frget the details of the subject matter along the way.
