The point is, unless we're all prepared to totally isolate from each other, maybe in little plastic boxes (one each), for at least two weeks, then these lockdowns are a waste of time. They are achieving nothing, except postpone things for a while. As soon as people start coming back outside, off it goes again. The only way ahead (without a vaccine) is to protect the vulnerable as best we can, and the rest of us just get on with things.
You can't send kids to school, students to university, workers to offices and factories, open shops and cafes...and not expect the virus to spread. It's madness. Everything we do is spreading the virus. But for the vast majority of us, it doesn't matter. But when you look at the steps we're taking, you'd think we were dealing with the bubonic plague, that might wipe us all out.
This country is on the verge of collapse, and we will be paying for this for a generation or more. Jobs are disappearing, businesses closing down, futures being demolished. Is it really worth it? And don't say "The alternative is that we all die" because we won't!
