I don’t think we should be in a haste of wanting bitcoin eliminate local banking services because satoshi didn’t intend that and I stand corrected but I think bitcoin was created to serve as an alternate currency which would help enhance privacy without a third party intervention but in recent times, people have chosen to make bitcoin more of a store of value than it’s actual purpose of decentralization and believe me, that would also make it very difficult for bitcoin to replace the banking system if there’s any possibility to that.
Even if people don't turn bitcoin into an investment, a store of value and use it for its original purpose. That doesn't change the fact that it won't replace banks. Because a bank is a large financial institution that is run and managed by thousands of people to be able to operate smoothly and provide many services to the economy. Meanwhile, bitcoin is just a currency like fiat or a store of value like gold, all of them are just tools. How can it compare and replace the role of banks?
I do not even think the top government officials would easily want to see bitcoin replace the local banking systems because most of their looting and corruption stealing are done through the local banking systems and it is more easier to cover their tracks through paper money than cryptocurrency which could be monitor through a blockchain.
This is partly true but I think the main reason is that adopting a decentralized currency would cause the economy to collapse faster. It is no coincidence that the world agreed to abandon the gold standard and replace it with fiat. The economy would face many limitations and challenges if it used a decentralized and limited supply currency like gold and bitcoin.
