Banking has been a pleasing guise, a pallatable mask for the exploitative expropriation of capital from those without to those with. It has been achieved through very artful, disingenuous and clever means.
Credit will of course still be required in the future. Even a bitcoin future. However, crowdfunding is still a New Thing. Who knows how credit will be found in future years - but something tells me it will be raised in a way more meritocratic than it is today.
When bitcoin says "the Emperor is wearing no clothes", the Emperor, once the spell of hypnotic inertia has been broken, is going to have to find a new legitimation . Bitcoin will chrystallise the question, if you like.
Maybe a legitimation won't be sought - maybe force will be used instead. But this in itself will be an answer of sorts, and a move forward. At least it would be honest.
Bitcoin can only do what it can do. It can't cure cancer. It can't usurp the Queen of England if the people want to keep her. It can't make a silk purse out of a sows ear.
But lets not downplay what it can do - and lets keep on believing, and telling our friends and relatives about it, and about banking and QE and boom and bust and fractional reserve - cos bitcoin
can achieve a lot.
Cryptograhers have very artful, disingenous and clever ways also - except theirs are now all open source
