I guess I overlooked the important bit of your argument. It was this:
it is impossible that the diagonal differs from all entries b_n at a finite place. If this was possible, the list would have a gap, namely a finite initial segment of d. That means, the diagonal up to every bit can be found in the list. And after every finite place there is nothing that could distinguish two numbers.
But there's nothing to support your claim that, if d is not in the list, then there is a finite initial segment of d not in the list.
