I don't think we are. Contractors and guns stores are open for instance. It is easy to make this argument, but it is a circumstantial one. The fact that restaurants and grocery stores are open allows for community spread. Half measures make little sense. The grocery and restaurants remaining open not because of science, but because there would be panic if they were not. It is troublesome how many people don't have a sufficient backup supply of food (or toilet paper, lol). Ideally letting people voluntarily decide if they want to leave their homes is the best option. Of course that doesn't give the government the control it craves.
