I think the argument here is that the SVB execs were "in bed" (so to speak) with the VCs who were pushing their companies to deposit at SVB, and the now-fired execs still have their recent bonus payouts. So the punishment is not spread out far enough to discourage moral hazard and future systemically-risky gambling with millions of dollars of other people's money. I'm not sure the same argument applies for the other bank(s) with huge MBS investments with lower yields than equivalent Treasury bonds. I don't know enough about those casees.
