Agreed - so much about the detail of how you would climb something comes down to details that would be hard to measure with a camera, like textures, your estimate of friction, etc. Very cool idea though, looks fun to test.
(Climbing rock without ropes may be more "pure" but is so dangerous that it should never be idolized.)
And then there's indoors vs. outdoors, with some dedicated outdoor climbers regarding anything done in a climbing gym as "not real climbing".
Most people don't take this literally, and it's generally considered to be a standing joke in climbing. Sadly, though, some people take it very seriously.
