However also remember that no controller will have all of the information that the pilot has and so it is not possible for a controller to second guess the reason for a pilots course of action.
True, but in normal operations (i.e. not an emergency situation for the aircraft), the controller is very likely to have the better overall understanding. No argument in an emergency but at other times the controller will simply be doing his/her job. If that entails instructing an aircraft to go around so be it. Of course, good practise would suggest that the pilot should be told why but a pilot who assumes that once cleared to land means the runway is theirs despite instructions to the contrary - the original question - is both wrong and foolish.
