Nope. The FDIC's main concern is with individual bank failure. If people spread their money out among many banks, then they have lowered both their risk and the FDIC's risk.
If you'd like to argue that the FDIC should go further so as not to subsidize people with shit-tons of cash, I'm certainly open to that. But the increased regulatory complexity might not be worth the total risk reduction, so I'd want to see some math. I suspect it's mainly a red herring, though, as I couldn't find any sign that Intrafi is a particularly large business.
