Please correct me if I'm wrong. As far as I know, there are many private banks, but in order to operate, they must go through and be managed by the central bank, and the central bank is directly managed by the government. So it can be said that the person behind the bank is the government. To me, banks are one of many tools that governments use to maintain the economy and control their people.
Answering OP's question, I never thought that banks or governments were against bitcoin, the role of banks in the world economy is extremely important and no one can replace it, including bitcoins. We don't need to exaggerate bitcoin and there are always hostile thoughts about why banks and governments are against bitcoin. If governments and banks against it, why are more and more countries legalizing bitcoin and bitcoin gradually becoming more popular?
You're not wrong, but at the same time he's also not wrong too.
Let's say the central bank ask any banks should follow 10 rules in order to allowed to operate, the private banks already followed the 10 rules, but it doesn't mean they only have 10 rules, because they can add more rules as long as it's accepted by the central banks.
That's why in a country where Bitcoin is legal (as a commodity), some people still ask the banks that friendly to Bitcoin since there are banks that restrict funds from Bitcoin.
