The whole point of de-centralizing a financial system is to move away from a central source for lending & borrowing. With Crypto currencies, it would be easier than ever for you to lend/borrow money to/from your friends/colleagues/investors etc.

The idea & support for transactions like borrowing, lending, escrow and likely all other transaction types that you can think of are already built into Bitcoin & it's design. They are just not being used as of today.

Infact, I would say it's safer to carry out such transactions using Crypto currencies than with a Bank. Please see this video: http://www.youtube.com/watch?v=mD4L7xDNCmA

Satoshi was clever enough to think of all use-cases and he made sure that the design & eco-system would be solid enough to replace centuries old incumbents like Banks. The features are just sitting and hiding there in the protocol to be made use of when there is enough traction & momentum.

I like bitcoin, but a government has the right to define the currency it's citizens use (i.e what is legal tender and what's not) and I think for a bank targeting ordinary people, you have to deal in legal tender. I don't think a bank for the 0.0001% who use bitcoin is going to be able to revolutionise banking..
