I can see this perspective.
I don't drink. Sure, on a special occasion, I might have literally one drink (I'm a lightweight, that's enough).
If a new campaign were launched today, to make alcohol illegal, would I support it?
Yes, because I don't need any more of you drunks sharing the sky with me. No legal alcohol = less access to it, potentially, so less people using it and flying. That's better for me, so I should support this.
Yes, because potentially less drunk drivers out there. Do I want less drunkies out there driving? YES. It keeps my family safer. We don't want to die because you can't control yourself. In 2014, drinking and driving killed 9,967 people in the United States! Holy crap! (source:

Yes, because my family is potentially less likely to develop alcoholism. Some alcoholics lie, cheat, and steal to get their booze.
Yes, because I don't use it, so why would I care if it were illegal? I don't buy it now that it's legal. Take it away, it does nothing but improve the safety of the people close to me.
No, because I believe in individual liberty. Do I want to stop the responsible people who enjoy a glass of wine with dinner, just because I know there are people who will become addicted, will drive and fly after using, and will kill people as a result?
In the end, I don't want the bad apples to spoil the good that other people enjoy, even if it's something that I don't approve of. If you have had alcoholism in your family, you too may not approve of the consumption of alcohol. I don't dig it, but I respect responsible people's right to put that in their body, if they so choose, as long as it doesn't hurt others.
So that's why I think drinking and driving should stay illegal (the behavior that is actually harmful to society), but just the act of drinking is OK by me, even if I disapprove of it.
