An umpire making a decision using that logic, or even making that statement after the fact, is waiting far too long to decide what the proper award should be.

I'm sorry, but I just don't have the clairvoyance to determine what the runner might have achieved minus the obstruction without letting everything play out.

Where does it say in the rules and interpretations that we must decide immediately what the proper award should be, and not deviate from that decision, no matter what happens next?
