Outside of having a vaccine, cure, or a widely-agreed upon, highly-effective treatment option within a matter of weeks, we are going to have two choices, one of two things will need to happen: Either the government will have to mass-produce the capacity (medicine, ppe, makeshift hospitals, ability to transport healthcare workers to where they are most needed -- essentially create emergency infrastructure) to care for sick to very sick people and reopen everything, OR keep things mostly shut down until such time as a treatment option becomes available and financially backstop everything and everybody.
This isn't an easy decision. Both are damaging to the economy, but the second option moreso. Lives will be lost under both scenarios, but less so under the second scenario. The first option limits economic damage but increases personal health risk and will cost more lives in the near term. The second option cost fewer lives in the short term, but I'm afraid more people will slip into poverty and more lives will be lost over time.
