Nobody disputes banks create the majority of the money. The dispute is on whether that amount is bounded (by some multiplier on Central Bank created money) or de-facto unbounded by a multiplier cooperatively controlled by the collective bankers, and probably even more specifically whether the latter has been impacted at all by the Basel accords.

Actually it is disputed, even 5th part of the video tries to address that. (Do banks create money or just credit?)

Which tries to prove that banks create money (not credit) cause money you put on bank is guaranteed by government.

But in reality, (even mentioned shortly on video), it is that your deposit is insured by banks via government.

"If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck.", whether you call the duck "credit" or "money".

And beyond the capped consumer risk the financial crisis was prove that the fragility of the interconnected banking system will be fully underwritten 'above and beyond' by the governments if push comes to shove.
