Once AI, blockchain, and improved means to use crypto provide even better security than governments and banks ever could, whatever they do will be irrelevant.
Why so? Do you think it's easy to topple governments just because AI and blockchain is taking over? I don't think so. We only need the governments and banks approval because they run the whole economic scene; their approval is somewhat valuable if we want to continue using bitcoin and other related services connected to cryptocurrencies without any restrictions and unfair limitations. They don't necessarily need to integrate bitcoin and cryptocurrencies in their infrastructure, but having them approve the existence, trade and exchange of bitcoins and other cryptocurrencies is a huge plus for the confidence of the masses who would want to try it out.
They run the whole economic scene for now because not everyone has accepted crypto, and rightfully so. It's not stable and a variety of things can turn south. Once escrow systems and distributed exchange networks are put in place, eliminating the need for exchanges that can be shut down by governments (or hacked), it will likely become the norm by default. There would no longer be a reason
not to take part and everyone would save a ton of time and money due to the efficiency of transactions and absence of fees. Businesses owners would also be at ease in each step of the supply chain not because of laws that can easily be broken but because of blockchain.
