The UK very comfortably missed the opportunity to go for the Swedish approach unfortunately by doing absolutely nothing early on. It would have been possible earlier but it's less effective than elimination, which is still a choice at that stage.On the contrary, Sweden managed to achieve 0.1% growth in the last quarter (UK equivalent: -10.4%) and doesn't seem to have suffered nearly the same sort of collapse across all sectors that the UK did. Had we adopted a Sweden style 'light touch' approach I think it's safe to say we'd have also fared a lot better economically.
I don't disagree that we needed to step in and impose a lockdown, and that some businesses were doing poorly, but I think it's a leap too far to try and conclude that a lockdown was necessary to save the entirety of retail
The UK is quite special in that we have achieved neither comprehensive suppression of the virus nor protection of economic activity.
