In my case, I'd be willing to exit the banking system in order to have true sovereignty over my money. After all, that's what crypto is all about. If you could live your normal life without the need to ever interact with a bank (having a bank account to make transactions, etc), it'll be a blast. With the world shifting towards the online realm for e-commerce, virtual meetings, and more, it seems likely that people will be using decentralized money more thoroughly. There are still people using credit/debit cards, but that may change soon as Fiat becomes hyper-inflated.
What are your thoughts?
I believe that as long as a country will maintain a central bank to regulate and monitor existing banks within their country, banks are here to stay.
Moreover, banks may still continue to co-exist with cryptocurrencies as long as the traditional banking needs of the people aren't totally replaced by other options instead.
Coincidentally, unless the country itself would declare that they won't be needing a central bank anymore, I don't actually see that it's possible yet to live without banks, in the traditional sense of what a bank is currently defined.
