[tsimionescu]

The article explicitly quotes the original source for this kamilos theory as claiming exactly this:

> ‘camel’: he doesn’t mean the pack animal here, but the thick rope, with which sailors bind anchors. He shows that the situation isn’t absolutely permanent, but makes the matter extremely difficult for him in future, and for the present, close to and neighbouring on impossibility.

So, even if you don't agree with Cyril's reasoning, it is clear that he believed that "camel through the eye of a needle" would have meant complete impossibility, but "rope through the eye of a needle" actually allows a slither of a chance.
