Here you go again. You make a supposition and then treat it as fact, and then build other stuff on that pseudo-fact. You suggested a simple shield that could/should do what you say. Run the experiment and then you can say it actually does it.

I made multiple correct predictions based on correct understanding of the subject.
If you think that the shielding I mentioned will not work it is your choice to test (run the experiment) and prove me wrong.
Derek made the experiment with all the results being correct but due to him not understanding the subject he came to wrong conclusions.
He noticed some energy flowing through lamp/resistor sooner than 65ns and he wrongly concluded that is because "energy doesn't flow in wire"
He had no idea or ignored the fact that a transmission line has capacitance (energy storage) in first video then when he found out he made a second video just mentioning that but not taking it seriously in consideration.
-Do you agree that making a cut in the wire will result in no energy transfer after the first few ns required to charge the capacitor formed by the parallel wires.
-When you also understand that shielding will get rid of that initial current through lamp/resistor but energy will still start flowing after those first 65ns you will know that energy flows through wires.

Has "how does noise voltage work then?" been touched on?

Can you be more specific ? Are you talking about an isolated circuit ?
Derek's real world circuit was not isolated from external influence but that part (contribution from that) was ignored. Was fairly small so easy to ignore.

Noise voltage across a bare resistor.
