Satoshi never mentioned that he created bitcoin to beat banks or replace fiat. If we use bitcoin as a currency and use it to beat the banks then that is our goal not bitcoin or satoshi.
This is so important and yet missed by so many people. He didn't do it to beat banks, or central banks neither, eh did it because he believed a decentralized currency would be a better way to use a currency, so he didn't do it to destroy anything, he did it to improve something.
Close, but not quite. Here you are still implying that he designed it to compete with normal banks, which is not the case.
Bitcoin was made for one reason: to allow people to transact who could not otherwise do so for fear of government prosecution. This was
never going to be a mainstream concern, which is why Bitcoin was never designed to scale past a relatively tiny number of daily transactions.
