To me that argument is a 'slippery slope' fallacy. We're not even close to that extreme. It's like saying let's get rid of mail in voting because there might be vast (non existent) fraud in the future.

And even if we go that far somehow I think the differentiation will come naturally. In climbing there is a totally separate thing called Aid Climbing where it's kind of like you say floating to the top haha. Pulling on ladders or whatever to completely eliminate strength and effort. It's not treated as remotely the same sport as free climbing.
