Drinking is harmful to human body. Why is it still banned by the state?

Moderate drinking is good for health. All countries have a history of banning alcohol, but under the final historical screening, they all keep drinking. It shows that although wine is harmful to human body and society, to a certain extent, wine, as a carrier of civilization and culture, is a way of human communication. Industrialization pollutes the environment and is more harmful to society. Why didn't you stop? Because we can't give up eating because of choking. Therefore, for alcohol and tobacco, we can only better advocate good habits, not excessive.
