It seems to me that if one approach is so politically unacceptable as to be quite unlikely, and the other approach is so politically acceptable as to be feasible, that is highly relevant. In the first scenario, this is just a hypothetical attack google could do if they were evil. In the second scenario this is a realistic attack we need to consider could happen. The difference between "hypothetical" and "realistic" matters quite a bit.
