> If this happens the companies will immediately close up shop. If their bank accounts get frozen for a week, they'll just lay everyone off and then hire them all back a week later with a signing bonus to cover their missed days. No one is going to permanently shut down their company because their bank is closed for a couple days. Maybe a few lucky executives will accidentally get their vesting accelerated, and a few startups that were on the brink of collapsing anyway might be pushed over the edge, but beyond that life will go on as usual.
