My point is say we all wear masks, thats fine by the way. We install HEPA filters in all buildings, we do another round of jabs, and the infections are still really high, we then move to the "ok, let's put a capacity limit in shops and pubs" . Jobs are then lost again, furlough starts again. That doesn't bring it down so we then close all non essential retail again, stop the live sport and music again. That doesn't do much, what next? We lock down, another 3 months goes by, transmission drops again, we come back out even more screwed than before and carry on. But hey presto, 3 months later were back where we are now!!
