A person must eat to live. But they don't have to eat a piece of chocolate cake to live. That's just pleasure.
A person needs to drink to live. But they don't have to have a beer to drink to live. That's just pleasure.
We can get by on very basic foods (rice, beans, greens and maybe some meat) but we enjoy more than that. We can also get by on just water but we enjoy drinking more than just that.
Really???? Read this article.

Longevity
Moderate drinkers tend to live longer than those who either abstain or drink heavily.
The National Institute on Alcohol Abuse and Alcoholism has found that the lowest death rate from all causes occurs at the level of one to two drinks each day.10
Drinking alcohol in moderation (1-2 drinks per day for women and 2-4 for men) was found to reduce risk of mortality significantly according to meta-analysis of 34 studies of alcohol and total mortality among 1,015,835 men and women around the world.11
An exhaustive review of all major heart disease studies found that "Alcohol consumption is related to total mortality in a U-shaped manner, where moderate consumers have a reduced total mortality compared with total non-consumers and heavy consumers."12
A Harvard study found the risk of death from all causes to be 21% to 28% lower among men who drank alcohol moderately, compared with abstainers.13
A large-scale study in China found that middle-aged men who drank moderately had a nearly 20% lower overall mortality compared with abstainers.14
Harvard's Nurses' Health Study of over 85,000 women found reduced mortality among moderate drinkers.15
A British analysis of 12,000 male physicians found that moderate drinkers had the lowest risk of death from all causes during the 13 year study.16
A large study of about 88,000 people conducted over a period of ten years found that moderate drinkers were about 27% less likely to die during the period than were either abstainers or heavy drinkers. The superior longevity was largely due to a reduction of such diseases as coronary heart disease, cancer, and respiratory diseases.17
A twelve year long prospective study of over 200,000 men found that subjects who had consumed alcohol in moderation were less likely to die during that period than those who abstained from alcohol.18
A study of more than 40,000 people by the Cancer Research Center in Honolulu found that "persons with moderate alcohol intake appear to have a significantly lower risk of dying than nondrinkers."19
