TVP, you are focused on a subset of the issues and thereby it is easy to spout what you are spouting.
Science is not simple and is evidence based (which means that opinions will change, such as with masking, how much of a shut-down, how long to quarantine, and whether schools can be safely kept open).
In March we saw a virus that spread very quick and was quickly overwhelming hospitals. The reaction to shut things down was conceived then, based on what other places had done already.
Over the following months and even currently we see a virus that does not seem as bad or perhaps the treatment is better. Very hard to say.
But history will tell you, that during the Spanish Flu Pandemic there were multiple waves and each one had differing outcomes. To assume this virus can’t get worse is simply ignorant.
All very nice for one person to say it is no big deal. Most Doctors who study this don’t have that naive confidence you and others do. It would seem that they advocate keeping social distancing, wearing masks and trying to mitigate the virus until a vaccine can be introduced and we see transmission go effectively to zero. Oh, and that vaccine is probably more likely to be effective the less strains of COVID-19 going around… Another reason to reduce transmission outside a vaccine as it will likely make that vaccine more effective and allow life, for those impacted by this, to get back to normal.
The flip side, like you, you can disagree. But let’s consider the consequence if the virus turns as bad as it was back in March or perhaps turns worse. The more people that have the virus and the less careful they are the more opportunity for deadly strains to emerge and spread.
Really, your complaints and whining about this, should have you consider this instead on a societal level and talk with doctors that are concerned about this and try to understand why. Of course, it is easy to sit in shul and ignore the numerous people who died (I kept track of the people I know that died from this and the number is staggering high in our community! We failed. There is nothing to be proud of how we dealt with this, unless you live in some sick and twisted world where having so many die and being the hardest hit community, probably in the world by this, is something to be proud of) and say the high-risk should lock themselves up and everyone else make believe everything is great.
