This is an interesting study, and I'm not 100% sure it supports their conclusion. For example on Figure 1 the hazard ratio for all cause morality isn't much higher than 1 until you get into the 200g+ groups, and the hazard ratio for cardiovascular disease is less than 1 until you get over 200g. This would seem to support studies that find a benefit for moderate drinking on heart health. Most of this benefit seems to come from lowering the incidence of MI based on Figure 2.

This also seems to support my initial hypothesis from reading your comment which is I wonder how much of the difference in all cause mortality is due to the effects of binge drinking or drunk driving. The fact that the hazard ratio on all cause mortality isn't really above one until you get over 200g would seem to support the idea that that is where most of the increased mortality comes from.
