I'm not sure that we (in the US) decided alcohol was fine from a liberty perspective, I think it was more the social consequences of Prohibition appeared to some to outweigh the evils it was fighting and to be somewhat ineffective to boot. For something as socially acceptable as drinking, it probably would have been better to take the sort of tack that was taken against cigarettes: increasingly high taxation, relentless educational campaigns beginning in childhood, advertising bans, regulation, bans on flavors etc., culminating decades later in total bans like what is now planned in some countries.
