The problem that I see with your argument is that kids will become carriers. Then their parents become carriers. No, many won’t die, but many will require hospitalization. And almost certainly grandparents will need hospitalization, and some would die.
Personally, I’m getting close to being on board with opening some businesses and letting people take their chances, What’s going to be different today than in 30 days? A vaccine? Not likely. I think that quietly, politicians have accepted that we have to let the virus run through the population, but that we also have to make sure it happens slowly enough for adequate health care for those that get seriously ill. Exponential illnesses can get out of control very quickly so I don’t begrudge Hogan or any other politician for going about this with extreme conservatism. I think letting kids play in groups though has the potential to quickly undo the good that last six weeks has done.
