Just for a minute, just a minute, think a few hundreds or thousands people would think like you " let's go to the beach, what could be wrong with it"?
You would have a thousand people on that beach, and it would only take a few carriers of the Covid-19 to spread it to more people. I go to the USA, and I know I cannot even bring a sandwhich from abroad, IT IS THE LAW! I abide. If I don't like it I would leave the country, or not go there in the first place.
