Yeah, I've never understood the logic that using Bitcoins insulates someone to the normal financial system. If you want a loan, put money in a bank account, or hedger risk, or do anything with your money that isn't just moving it from address to address, it is still needed to have banks.

Or have cryptocurrency fans figured out a solution that I can't think of now.

It's similar to the idealist trope that tearing everything down to rebuild it will somehow not be subject to corruption and perversion the next time around. As though they've found some way to control human nature. It's unavoidable systemic entropy.
