I'm in favour of having every economic and social activity allowed that can be safely open, which I think means -
1) Any activities which have no risk of passing on the virus whether the person carrying them out is negative, asymptomatic, symptomatic or recovered with antibodies. These will mostly be solitary and/or outdoor occupations.
2) Any activities necessary to human and animal life -farming, food, medical, etc. Persons carrying these activities out should take all practical precautions, including having regular testing, appropriate PPE, social distancing where possible, keeping records of contacts for ease of contact tracing if they test positive.
3) If infection rates in an area are past the top of the curve, then activities which are not strictly necessary but where risk assessments (a process familiar to all activities subject to health and safety legislation) show that the risks of spreading infection can be limited and controlled, again with all participants taking all practical precautions, including having regular testing, appropriate PPE, social distancing where possible, keeping records of contacts for ease of contact tracing if they test positive.
4) Some activities will be risky in any circumstances where the virus is still circulating, such as large ticketed events (sports, concerts) or large groups singing. These may need to be heavily restricted in attendance - for instance, limiting attendance to residents of areas with no known infection risks.
5) Enhanced medical, economic and social support systems will have to become the norm for those most at risk from the virus.
