Tho person you replied to didn't say 'ban' they said 'regulate' and 'a larger plan to combat obesity', and your counter of alcohol is heavily regulated across the world. Some have government run shops, others have advertising bans, or mandatory health warnings, alcohol content labelling and so on. And probably in general should be more regulated.
It read like a ban to me. Other than age restrictions, which vary wildy, it doesn't seem like alcohol regulations have done anything to prevent unhealthy use.
Then you need to increase your reading comprehension. I nowhere said or implied "ban".
Or you need to examine your biases; are you perchance a libertarian? Or really right-leaning in any way. If you're American, chances are very good the answer is 'yes'.
