Do you really think that how Organ Pipe chooses to climb Kachoong (short of manufacturing holds or sticking in those ghastly ring bolts) makes any difference to you or me or anyone else apart from Organ Pipe?
Who gives a sh1t if he wants to top rope the sh1t out of it, have someone else place the gear and then pay someone else to climb it with a helmet cam? Is the eleventy billionth ascent of Kachoong a significant event in Australian climbing?
There is a difference between ethics and style. Ethics is what you do to the route, and style is how you climb the route. Climb in whatever style you want.
PS Organ Pipe, Kachoong is one of the easiest 21s at the Mount (in my experience) so hook in bro. You'll be right.
