Yes, that's the worst case - however in the real world the FDIC and the OTS (Office of Thrift Supervision) does their best to ensure nobody loses any amount of money regardless of their account balance.

That's how we found out our backups (made with the very expensive backup software Alexandria) didn't work. And this was well before Git, so we didn't have multiple redundant repositories we could sync from to recover. The humongous NetApp rackmount RAID was 35 gigabytes if I recall correctly.
This is a problem with improving reliability through redundancy: sometimes instead of getting reliability, you just shift the failure modes to more catastrophic systemic failures, because they happen too rarely for people to assess the risks properly.
Speaking of systemic failures, everybody who's had US$10k in the bank since last year (or in other dollar-denominated assets such as T-bills) has lost US$800 of it to inflation over the last year. What else could you have you spent US$800 on? If your retirement fund has US$100k in the money market that inflation cost you US$8000.
Still, be glad you're not in Argentina. Our central bank printed a trillion pesos last month, a quarter of the monetary base, and the inflation over the last year has been about 60%.
