Eventually everyone either (1) gets it and has none or mild symptoms, or (2) gets it and requires hospitalization if available and then either recovers or dies, until (3) there is a working vaccine available in quantity for those not yet infected. Dealing with (2) is the biggest issue and that requires masks, gloves and ventilators and universally available free testing. (3) will happen eventually but not right now. Social distancing helps with (2) until we have enough capacity to help them, which is the major problem. But you still have to have food to eat and a place to stay and that requires some measure of assistance, logistics and production and distribution still functioning. Once you can deal with (2) if everyone was careful (which isn't happening) you could function until (3) with some limitations.
