Actually there are lots of finite sequences of digits that define numbers quite effectively,

It is those who claim that the set of digit strings is countable who must create that allegedly impossible listing to prove that that set satisfies the definition of countability.
Any set whose members cannot be 'listed' is, by definition, uncountable.
If WM chooses to say that the set of real numbers, or the set of endless binary strings cannot be listed, then it is WM who is arguing that those sets are uncountable. > > > > What drives WM is shear orneryness. > > What is that? The necessary quality for membership in your WMytheology.
