What about services like plumbing/appliance, or auto repair? I think those have to be allowed to operate because people can come across massive hardships and health risks without them.
I think once you eliminate congregational or group recreation type things (gyms, theaters, bars, malls, carry-out-only for restaurants, etc) you can't do a straight up shut down here without causing more harm than the risk the virus presents. We rely so much on a myriad of services that are necessary to keep our standard of health and functionality going, that it's tough to just draw a line in the sand once you get past things that have truly non-essential functions (like the ones I listed) in our society.
