Why not? Indeed, it would be systemic. That's what needs to happen. There are and would still be deep pools of capital that would be employed as failed businesses get restructured or acquired for pennies on the dollar. Sure, you'd get some duration of absolute dislocation (huge bid/ask spreads on virtually everything), but once the shock wore off, people with cash would have a field day picking up cheap assets and businesses, and things would ultimately turn around quicker than what's happening now (and which will continue to play out for years/decades).
