This idea that it "fits my narrative" to see the country screwed by lockdown is complete nonsense. I don't even see the point of trying to refute it: it's an outrageous suggestion with no basis in any fact whatsoever, and I invite you to come up with a better counterargument.
I do know that, earlier in the year, Gupta published a model that suggested well over half the country had already been infected by March -- a model that was certainly flawed in many of its assumptions. In May, she also said that the epidemic was "on its way out". Well, it's back now, with a vengeance.
I do not presume to comment any further beyond that. She is an epidemiologist, and I am not. All I can say is that the weight of medical and scientific consensus is against her, and, as far as I can tell, the weight of the data is too. This alone isn't enough to refute it, I know, but I don't prefer one narrative to the other because it suits me. Nothing about this year has suited me, although I have been somewhat lucky in many ways. I'd like point out that, as a young, healthy person with a history of shaking off most infections with relative ease, the virus probably poses virtually no threat to me personally.
Over the Summer, I was hopeful that the data were supporting the idea that the Government had brought this under control, and hopeful that the easing of measures had been done in the controlled manner required to get the country back on its feet without the risk of a Second Wave. That's been sadly blown out of the water.
