"And, he may feel that, this late in the game, an ablation might not help you because it would involved a horrendous amount of lesions in order to block the signal.

You are darn correct that this is all conjecture. This is a step too far to suggest to someone when you are not a medical professional and should not be writing words like "horrendous amounts of lesions". These are not the words of anything I have ever read in a medical journal. This is not sound medical advice.
