I think targeted redistribution will work better. If you want to protect the economy, take the people with excess wealth — providing no utility right now — and give some of their wealth to those who cannot earn income during this crisis. It avoids the inflationary effects of printing money. You could accomplish this by raising taxes on the wealthy and sending the revenues directly to those who will lose their livelihoods and the small businesses which need to make rent to stay afloat. Obviously the political appetite to do this doesn't exist in the US, but I think it is easily the best solution.
