I'm with Plant, beer and wine
are food.
In many cultures within the United States, it is common to drink a glass of wine or a pint of beer with dinner. Drinking hard alcohol with dinner is much less common.
There is a distinction between vodka and beer, just as there is a distinction between heroine and marijuana.
Treating them the same ignores the culture surrounding them.

Americans, as a whole, have significantly cut their alcohol consumption over time. But most of that decline was in spirits. Hard liquor consumption is down by more than a third while wine is up and beer is basically flat.
This is partly the result of cultural factors and partly the result of harsher government tax treatment of spirits.
Equalizing (and raising) the various alcohol taxes could have the unintended consequence of making hard liquor more commonplace, not less.
