They haven't faced up to the two fundamental choices:
1. Largely restrict people's freedoms to live as they want to. This needs to be done for an indeterminate period of time, until there is a vaccine or effective treatment. At that point, either the country will be bankrupt, or there will be very few theatres, museums, cafes, restaurants, heritage railways etc left to enjoy. Probably both. Mass unemployment, and the devil's own job to kick start some kind of economy. Probably more death through a huge contraction of the NHS and social care.
What if there is no vaccine or effective treatment found? What if the country goes broke before that point or soon after? What then?
2. Properly protect the vulnerable, accepting some will catch covid and some of them will die from it. Allow normal activity to resume. It'll be ugly for a few months but 99.5% of us come through the other side and still have something recognisable in terms of society, economy and leisure activities.
