If an average person were laid off today and couldn't find a job for 1-2 months, would they go bankrupt? I think most people would be able to survive on their savings for a month or two. Companies should also be held to the same standard. They should have enough savings to survive this sort of disruption, just like a person would.
So yeah, if your company can't survive a month without revenue, it is a crappier than average business.
