Every node is such a node at a last level. This is the nature of the
nodes. Nevertheles there is no last node.

The tree of all finite paths and the tree of all paths like every tree
has infinite paths. Therefore there is no tree which has only finite
subsets that are considered paths.

Is this tree
0 1 0 1
that one with infinite subsets not considered paths?
