I dont really know what you are asking - keep businesses going rather than scale back? Who pays for that and how - the government is already racking up loads of debt, and there will be lots more industries affected by travel disruption, as well as support businesses like engineering companies etc...
The economy would have been screwed whatever we did, although the extent would vary - but RR isnt down to the government, its other countries having travel bans/quarantines etc... Even if we had done everything perfectly and only 1k had dies, and R was 0.1, but the rest of the world was as it is, RR would still pretty much be in the same boat.
