Undefineable or unreconstructable paths are not needed to prove
uncountability because every list of defineable/constructable paths
proves the existence, by explicit definition/construction of it, of a
path which has been omitted from that list.
Thus it is your alleged set of all defineable/constructable paths that
either does not exist at all or is not countable.
