There is an answer to my question but its one your not willing to consider. They used CA because that's all they had pure and simple. But we have so many methods at our disposal that one can now be orthodox and adopt any number of methods and we're all "kosher" so to speak. If you adopt that view it alleviates the problem and we can all be orthodox and debate which one's better. Thats the only way out.
If not than answer the question, here's a simplified version how would a pizza be different if CT weren't true? Would it even exist at all?
Of course there are more methods. That doesn't mean that presup is correct.
