The amount of effort it would take, push-back and crime it would create and would not save many people. How many alcohol abusers would switch to smoking or over eating junk food? Probably a lot. While alcohol causes 95K deaths, smoking, obesity, bad diet kills way over 1 Million.
So if saving people is the goal you would want to ban nicotine, and all junk food, sugar and so on.
An estimated 95,000 people (approximately 68,000 men and 27,000 women) die from alcohol-related causes
Unhealthy diet contributes to approximately 678,000 deaths each year in the U.S., due to nutrition- and obesity-related diseases, such as heart disease, cancer, and type 2 diabetes.
480,000 deaths from Cigarette smoking annual
People have rights. Obviously banning sugar is absurd. You can push leaders for more education about health and alcohol. We do not need more right taken away from us. If someone wants to ignore their blood pressure, gain weight, eat bad and then has a heart attack at 40 it's their choice. You can try to steer them in a better direction. But taking away rights is not the answer. You don't use alcohol so it seems fine to you. How about if they took away all sugar foods, high saturated fat, desserts and so on? Kills far more people?
It isn't the answer. Also the jails would be full of regular people who got involved in underground alcohol distribution. Some would get repeat offender and so life sentences. Do not give the government more power.
As it is drugs should be legal at a clinic that includes counciling. This has worked in other countries. Low death rate. Meanwhile in the US people are dying of fentanyl laced heroin every day or getting arrested
