That'd still be "recreational use", not as staple food

Is anybody in this discussion advocating alcohol as a staple food?

A staple food is something that makes up a dominant portion of one's diet; it's beyond a mere common or everyday food.

    A staple food, food staple, or simply a staple, is a 
    food that is eaten routinely and in such quantities 
    that it constitutes a dominant portion of a standard 
    diet for a given person or group of people, supplying 
    a large fraction of energy needs and generally forming 
    a significant proportion of the intake of other nutrients 
    as well

I would certainly agree with you that alcohol is not a very safe choice for a staple food!
