Currently, those businesses can't plan on anything a month away. There could be demand or not, supplies or not, workers or not... nobody knows. Demand is crushed and never returns... Now consider the alternative. You know that you will be open in 2 weeks, you know when you need get parts there, and you know when demand will show up. You can still use some amount of "essential" work at the corners. The point of the two phases is to make sure that things don't blow back up again and to make it obvious to everyone that it's fair. Then, demand is shifted rather than destroyed and the economy can function at slightly reduced capacity while still keeping the viral contagion controlled (not some crazy let's hope there's herd immunity and let everyone get it, or we'll keep the ICUs full for 18 months and hope the immunity lasts that long).
