Some activities, like playing loud music, unavoidably intrude on others enjoyment.  Yet in I suspect the vast majority of cases citizens who picnic and drink a bottle of beer or hard lemonade cause zero intrusion into the enjoyment of others.  Those who do not like to even see someone drink a beer must deal with their own desire to control other people which is not a good quality.  Pass laws banning those things that intrinsically intrude on other's enjoyment.  Let us retain our freedom to do those things that do not.
