I think you are missing the point of this thread. The post is about future possibilities.
What can a pilot do about contaminated fuel that a pilotless plane would be incapable of doing in ten or twenty years time?
Any way, even if the scenario you describe defeats the pilotless plane this is not an argument against automation. If automation prevents the type of crashes currently being discussed on this forum and that leads to an OVERALL increase in aviation safety then we all gain. Just as the old anecdote of a driver being "thrown clear" from a car accident is not a valid argument against the wearing of seat belts!
