Minimum economic damage was ALWAYS going to be caused by locking down sooner and harder. If we'd done so 2 weeks prior, and stopping fucking about with allowing crap like Cheltenham to go ahead and then when we did lockdown, not with this "it's ok to go out to exercise" bollocks, the peak would have been several weeks ago and we'd be very near to opening up pubs and restaurants again. The period of disruption although more severe would have been much shorter and survivable by more businesses.
That it has gone on - and will go on - as long as it is, is entirely due to the peak being bigger and taking longer to peak, because it's a bigger peak. And longer to decay back down again.
We could have simply hit the <pause> button on the economy, the government paid everyone for a short period and then we'd be back to some semblance of normality quite quickly. And the economy would bounce back.
This is still the best approach, we just made it more difficult. The sooner we have this thing under control, the sooner we can start getting back to normal and restarting the economy with the minimal of businesses lost. We do not minimise the length of the lockdown by allowing a few businesses to limp along. It actually hurts them more in the long run.
