Except that there are many commenters in this exact thread making that argument.

As for splitting up your deposit into $250k chunks, I agree, companies should do this as much as possible. But it would be hard for some companies. An extreme case is Circle, who says they had $3.3 billion in SVB. To get all of this covered, would require 13,200 different banks. It looks like there are only 4,236 FDIC-insured banks in the US. Add in another 4,853 NCUA-insured credit unions, and we're still left with $873 million uninsured, despite using nearly 10,000 accounts.
