Point 1 is happening with fiat A LOT. So does not apply.
Same for point 2... not sure what an intermediate should add? A company doing this will be out of business pretty quick...
Point 3 idem... if i send money to a whrong bank account... i am at the mercy of the receiver.. no bank will reverse it...

This is based on EU by the way, we do not really use credit cards here
