So we still need to develop more blockchain networks that would completely eliminate the banking sector.
You are right. However, the state will protect the banks that issue fiat. Countries in the world will not let fiat currencies as their country's identity be replaced. If you call this a war, this is the same as fighting the country itself.
After all, why do you only want to get crypto with fiat? If you want to have crypto without going through a bank, you can start accepting crypto as part of the payment for services and sales of your goods (if it is not contrary to the laws in your country). It can also be applied by people all over the world to gradually want to eliminate the role of banks from life. Of course this is not instant but it is effective in reducing dependence on fiat currencies until it is no longer needed.
I have learnt a lot from you today. It is good thing to start accepting payments through cryptocurrencies. There is no financial freedom as far as the USD is used as a tool in international marketing. Cases where just a $100 is worth N39000 in my country.
As long as crypto adoption is here, there is no limit to financial freedom, it is almost more secured than Banking with banks. I wanted offer a service for a client staying in the states, he literally didn't know how to use Bitcoin. I tried to explain to him it actually proved abortive.
Yeah after accepting payment through crypto you will still look for local exchanger to exchange to naira because as far as crypto acceptance is concerned only few merchants online can accept it, buying things from your local stores will require spending bank note (naira) which you can't do away with,
Probably if the naira was not devalued to this point by your government, $100 will equal N100. Between I don't know what is so bad in bank that everyone is against it, crypto is not free too with all the scams involved.
