Either the tree is not a binary one, or it will necessarily contain at

least one infinite path

Here is the schematic for a binary tree with one and only one path of

each positive finite length.

Note that it also and necessarily has an infinite path of 0 nodes.

Root

and so on, ad infinitum, each 0 node having two children and each 1

having none.
