The thing is .. the FDIC is already funded by banks.
https://www.fdic.gov/about/what-we-do/index.html
"The FDIC receives no Congressional appropriations - it is funded by premiums that banks and savings associations pay for deposit insurance coverage. The FDIC insures trillions of dollars of deposits in U.S. banks and thrifts - deposits in virtually every bank and savings association in the country."
How the banks choose to pass that cost on to customers/shareholders is up to them.
It's instructive to read https://www.fdic.gov/analysis/quarterly-banking-profile/qbp/... for the last available quarter; the insurance fund is on page 24. I can quote you two numbers and you can decide whether they are big or small: there is $128 billion in the fund, and this covers 1.27% of total US banking deposits.
Surely the logical counterparty for the insurance is not the bank, but the third party insurer? i.e. that people should explicitly have to pay for FDIC coverage themselves?

This is basically a credit default swap for bank accounts, and if you wanted to insure the reported $450m that Roku allegedly had with SVB, someone would have sold you a product I'm sure.
edit: remembered "insured cash sweep", which is the product that everyone should have been using. See https://www.intrafinetworkdeposits.com/ or https://www.cbhou.com/Resources/Customer-Corner/entryid/237/...
The money pipe was opened then and SVB showed it will never be closed. The capture is complete.
