I am not confused and it is a fact that thinking of information as
something physical has over the last century proven itself to be
remarkably fertile and has led to the discovery of new knowledge,
while thinking of information as ethereal was found to be sterile
and has led to nowhere and nothing.
False. All the radio and tele-communication have come from the purely
mathematical theory of Shannon.
Only with quantum mechanics, some physicalists, like Landauer and
Deutsch, explore the speculation that there might be a notion of
physical information. But to define it they still rely on Shannon and
Turing purely mathematical notions.
Also, don't use "ethereal" for immaterial, especially after asking if
natural numbers need a reason to exist(*).

A better question is do the natural numbers need a reason to exist?
I don't know the answer to that but my hunch is no.
