Honestly, there is no answer to that as everyone has their own incentives and needs to deal with. Government officials are in charge of the safety of their represented population, and also the economic outlook of their represented territory. Individuals worry about their personal health. Business owners are fighting to stay afloat.
Taking it from that standpoint, there has to be some middle ground such that those who are willing to work despite the risks are able to do so, without putting at risk those who wish to preserve the health of their families. I believe that what the government is currently doing, focusing on low risk communities and industries, and slowly opening those up while monitoring the response, the best case scenario. The last thing we want is a second outbreak and to do this all over again.
A major concern is that the business world is an ecosystem. Cut one link in the chain and the entire thing falls apart, employees aren't getting payed and can't finance their living conditions, land lords don't get payed and go into debt, banks can't collect on debts and re-funnel that money back into the economy. With this in mind, policy makers have been the major spender to prop up the economy, preventing those links from breaking, and they are the ones eager to restart the economy to prevent further damage and or a recession. As it stands, the thought that businesses can restart, rehire all their employees, and gain the customers they once had to create a "v-shaped" recovery, is hopeful at best.
But I'm just a math tutor so what do I know :)
