While I would agree with you that sitting on a beach in and of itself is not harmful and may well have health benefits, that's not what the ban is sbout. Extreme measures unfortunately have become necessary to flatten the curve of this deadly virus. The problem is the people that think their judgement s better than the trained professionals whose job it is to protect us from ourselfs. Bottom line, obey the directives issued and think of others when you don't want to comply with what you think is unnecessary.
