I can kind of see both sides of the argument here. I think the point that NN is (imho) trying to make is that it would be nice if the CAA devoted as much time, effort and zealous rewriting of the FTL rules to address the severe flight safety issues caused by fatigue (which affects all crews) as they have recently devoted to rewriting the alcohol rules to address the flight safety issues associated with alcohol, which I would suggest has affected a far smaller %age of crews.
I do think that safety would be improved far more, far quicker if fatigue was seriously and maturely recognised as the potential killer that it is and legislation enacted accordingly.... but that would affect profitability and will therefore never get past the "Old Boy Network" of resistance. As far as fatigue is concerned, I fear we are going backwards and letting commercial pressure drive safety standards...which must be wrong.
