Hopefully if the shareholders loose a lot of money this way, they will demand better governance of the next company that is set up. This, at least, is how it _should_ work.
How would better governance help? This is a once in 50 years event minimum and losing all your custom for three months is enough to wipe out the accumulated profit of a decade for all but the most well capitalized businesses, with no shareholders clamoring “Where are my goddamned dividends?” It’s not like you can take insure for a risk like this either. There’s a substantial risk your insurance company and their reinsurance company will go bust.
