As if the lack of consequences for perpetrators doesn't have consequences of its own. Insurance is not free money.
Their point was that they aren't worried / don't lose trust in the bank if it gets robbed. Rather, the money is guaranteed, so they retain confidence in the bank even if it loses a lot of many due to a particularly successful robbery. Because they'll still get their deposit back.
This is 100% what the FDIC and NCUA are about: ensuring continued consumer confidence in their banks.
I think many would lose trust in their bank if they heard it was being robbed with abnormal regularity.
It's also your perogative to shop at shady websites, and hope your credit card will accept the fraud claim. It basically the same thing.
In no way do I condone robbery.
