It is obviously impossible to find any path in a tree when that path is
not in that tree.
But WM cannot prove that that path cannot occur in a COMPLETE Infinite
Binary Tree, because it does.
If that path is not in some tree, it is because the tree is incomplete.

If no binary sequence for 1/pi exists in WM's Complete Infinite Binary
Tree, there must be a first node at which the infinite binary sequence
for 1/pi from every path of length n in the tree.
I.e., there must be a first binary digit at which the binary
representataion of 1/pi differs from every binary sequence.
And thus there must be a finite binary approximation of 1/pi which does
not appear in WM's tree.

WEven though there are only countably many nodes, there are UNcountably
many sets of nodes, and paths are SETS of nodes.
So countability of the set of nodes does not imply countability of the
set of paths, but tends to contradict it.
Thus, once again, WM's ability to keep thing straight is found wanting,
and his arguments found flawed.
