Beer tastes like shit. Nobody likes beer, it's just another taste learned through peer pressure. And bread tastes good, therefore beer can't be liquid bread
This is quite wrong, a lot of people like beer. And apart from the taste (which I'm not going to argue about as it is pointless) beer has many advantages.
I'm not even comparing to the unhealthy sugarthingies the kids drink nowadays.
Beer is usually served either in bottles or large glasses which are relatively sturdy when comparing with say wine. Due to lower production cost of the glassware, lower breakage chance and more uncomplicated serving beer allows more freedom and activity. Their larger tanks also let beer drinkers operate further from the bar. Movement is healthy.
Out of all traditional drinks beer has the lowest amount of alcohol per liter and also works quite fast. This makes it very easy to dosage. Easy is maybe wrong because it tastes so good, but unless you are drinking very fast your body has time to realize how drunken you are and whether you'll regret the next one.
It is also significantly more healthy due to the amount of water, nutritients and Spurenelemente it contains. One of the chief dangers of drinking is dehydration and the loss of important elements. While the intake may not outweigh the loss it does limit the bad effects better than any other drink. Since quality beer causes the least amount of hangover per liter of alcohol (with the exception of quality vodka perhaps)
[1] productivity is retained as best as possible.
Bottom line is beer allows to reach the desired state of drunkenness with the highest accuracy and the least harmful social, economic and health side effects. Even if it did taste bad it would be the most sensible thing to drink.
