It means that all nodes and edges are constructed with countably many
finite paths. It means that if you want to distinguish an infinite
paths from all finite paths you cannot do so by nodes or edges. And
that's a lot.

But unfortunately they are not defined by nodes. Every node that you
may want to use to distinguish an infinite path from all finite paths
is already occupied by a finite path. If you wish to prove that
infinite paths are more than the union of finite paths, than you will
fail. If you agree that infinite paths are only unions of finite
paths, then you agree to potential infinity or limitis that are not
defined by nodes - and that excludes uncountability.
