Earlier quoted context omitted.
"Social experience at feels contrived and not everyone may want it." This pretty much sums up _everything_. So, why do we even try to have societies? Edit: You use an example of going to a bar. You realize "... not everyone may want ..." to socialize at a bar? Some just go to drink.
The point of a bar is to socialize, or at least have company. Otherwise why not buy a bottle and stay home?
May be the stigma of drinking alone, where one is sometimes considered a drunk if one drinks alone.
