Eh, normie world still exists and I still have to interface with it. Bank account is necessary.

Here is a new Legendary Meme inspired by you. To me this is the only acceptable interfacing with banks for Bitcoiners.
I try my best to avoid the Normie world as much as possible. I stay my happy ass in the mountain wilderness. I've been able to get by for a couple years just fine without a bank account. Even though it can be a big pain in the ass at times. It is possible to live without one.
Surprisingly crypto exchanges have become the closest thing to a bank account that I have. I do not even keep any money in it except for what I need to use at the time via a debit card by converting Bitcoin into USDC to load it up. Makes me feel sick to my stomach, but thankfully I haven't had to do that in awhile either lol.
