Surely the whole point of social distancing was to keep people safe until the NHS is in a position to cope with a steady, ongoing influx of people who have contracted Covid19.
So ...
The most vulnerable - ie those over 70 and/or with underlying health issues are know to be more at risk, so they should isolate for a further period. Fortunately, many these people are generally retired and so not needed with quite the same urgency to restart the economy although they may wish to socialise with others who have been in total isolation to keep themselves sane!
Others need to get back to normal asap (but still taking care - ie working from home where possible etc). A proportion of these people will, no doubt, contract Covid, but the hospitals will be better able to cope and once a significant proportion of the population has had it and recovered we will be into the herd immunity stages.
As we have all (mostly) been isolating it will also become easier to trace the source of the infection and ensure all contacts are then isolated as far as possible.
There is no easy solution, but I believe the above is what the government has been aiming for and largely I can see the sense in this strategy. For now we can only be careful and stay safe.
