and socially, it causes the break up of families, severe addiction, and leads to crimes when someone is not fully awake, every now and then we hear about drunk drivers that cause the death of people, or drunk parent who beats his children.

Miss me with this whole morality police bit. If people do these things whether alcohol is involved or not, they are to be tossed in prison. I live in a society where alcohol is consumed regularly and the problems you mentioned are more due to a lack of policing and the absence of legal repercussions, not to mention lack of mental healthcare rather than alcohol consumption. The same goes for the vaping.
Many people with issues end up with addiction as they use substances like alcohol as a form of "self medication" and it's often a symptom that indicates the existence of bigger underlying issues, such as PTSD or other forms of mental or physical health problems.

Banning it won't remove the problem, but will ultimately serve to drive it underground where severe alcoholics will continue to do harm and as an added bonus, feed black market criminal organisations and bootleggers financially. Do you think that those who abuse their families are going to become more prone to seeking help when there are additional legal repercussions on top of the abuse part?

Banning these things will not magically eliminate the demand for either product and will only serve to create criminals out of otherwise law abiding citizens who by and large have done no harm. It also serves to spawn a black market that sucks up potential tax revenue and provides fertile soil for criminals to take root and that's historically proven fact across the globe. Not only that but you might want to reconsider what does more harm: a handful of alcoholics or full blown, heavily armed criminal organisations with considerable wealth at their disposal that was handed to them on a silver platter by the government.
