Yes, but if there's an axe murderer in my house, I don't care how much he intends to murder me. I don't want him to murder me.

The government has a variety of aims and objectives. Certainly, shooting for a more healthy population is good. Convincing those that drink a lot to drink less would be one way. Permanently making the drinks awful for the entire population, no matter how many or few they drink, and ensuring what was once good never ever comes back... is another way.
