Not within any common axiom system. And WM's axioms, those things he claims but does not and cannot prove, are not truths in, for example, ZFC, in which the axioms are at least explicit. > > > > (3) To consider countability of the finite initial segments FALSE, > > i.e. to say that we have uncountably many finite initial segments of > > reals and as well we have uncountably many reals.

While that may be an incomplete listing of nodes, it is certainly not a listing of paths or of initial segments of paths, other than possible the root node as a one element path.
