There's little point in acting as if working life can stop beyond what's strictly and immediately life sustaining. For a week (for most people) life's about food and water, but that's not enough for long.
We're already starting to get used to how dependant we are on a massive infrastructure that deals with health, education, food production and distribution, utilities.
Stop collecting rubbish for a couple of weeks and we'll realise how dependant we are on that. Same with the chemical industry and engineering firms who underpin the rest of it, including health services and food production.
Same with a whole army of jobbing builders, roofers, plumbers and electricians who fix all the stupid stuff that goes wrong in people's houses - ironically often in the homes of the old, and the vulnerable who don't have the money/energy to deal with routine maintenance or replace a boiler until it actually fails completely.
As time goes on, shoes for growing kids are a necessity. So are lots of things.
Complaining about people going to work is pointless. Lots of people need to be working to support our lives, at different times the numbers will be different. Right now the priority is to avoid destroying the health service.
People getting infected in this period is inevitable, and that'll continue to happen until we have a safe, proven vaccine. It's going to be a balancing act - and yes, that does mean people will die, the balance comes when you look at the alternative. We also want the farms to get their annual influx of labour and pick the soft fruit, or the builders to take the cladding off the tower block and install sprinklers, and that the suppliers need to be open to support it.
What we can also try to do, is remember the lessons. Working from home, social distancing in the workplace (flexible working hours, less crowded cafeterias - anything that makes queues shorter). Those can continue as well. Meanwhile, home delivery for the most vulnerable, could be become more of a routine, and less of a crisis. Balance is a big deal.
