I think it is difficult in this world without having your own bank account, especially if you are an employee, so your net earnings will have a destination that here you will receive it. In banks, here we sometimes borrow money or take a loan for us to buy things that we needed the most such as opening your own business or buying a new property. It is the reason why the government will not let bitcoin and cryptocurrency reign in the future because people still need banks for their daily lives.
We all need fiat and banks to live a normal life but I guess living on crypto can have many different meanings like for someone like me I pay my bills, recharges and everything possible with money earned through bitcoins which should count as living through bitcoins because not directly but all my expenses are being done because of bitcoins. I don't pay in bitcoins but I use bitrefills for recharges and I use some local services for my bills or if they are not active I try and exchange for fiat my coins and pay them.
Living bank-less can be near impossible in a country like mine because you cannot get enough digitalization in coming years here and cannot expect people to accept payments digitally let alone bitcoins or crypto. Most of the people here in my country want to save tax and they would always prefer cash so they can save it and avoid tax and in such situations you can't live on crypto completely.
