Why won't you address the arguments?
Really. You have a problem. I think I have addressed arguments people have put forth. The bottom line is that the impetus that drove the ball into the endzone was supplied by a defender. There are no exceptions in the rules for fumbles as there are for punts. The rules for touchbacks and safeties both suggest that impetus is important. One would seem to indicate that the play could not be ruled a safety; and the other would seem to indicate that it must be ruled a touchback. In other words the two rules are consistent. I didn't make them up. I just read them.
