Forget bank runs. Banks are corporations and corporations can fail. Very few people have cash above 250k. Financial advisors routinely advise protecting against bank risk by buying risk-free assets or using CDARS or equivalent.

Ironically, it kind of seems it may more likely for a consumer to protect against bank risk than for these startups and VCs that, despite all their resources and CFOs, apparently had collectively decided bank risk isn't a think for them.
