There is no current in the shield inner surface, the energy is in the

surface current is insignificant.

this is a pretty amazing revelation. So what are the assumptions to
make this true?

Do you think there is significant current in the walls of a wave guide?

You keep posting the same link which offers nothing to support your
point. So I have to assume you don't have any reason to believe there
is no current flow in the coax.

You keep responding to questions with questions. If you actually
understand this stuff, do you care to explain any of it?
