While I can see your point, think of it anotther way...
Police officer arrested for drink driving...Will be sacked.
Train driver arrested for drinking driving train....sacked.
Captain of a ship (irrespective of if he's driving it at the time, or asleep in his cabin) ...sacked.
Those are 3 examples of many that will loose thier living for a similar offence. Why then should a pilot be any differant?
Much as been said of monitoring etc, but monitering by other crew happens now, and still there are arrests/convictions for drinking & flying, so it s not a deterrent. I think that this new law is exactly that, a deterrent.
