I think you're missing the point.

The revolution is not cryptocurrency. The revolution is blockchain. Blockchain will usher in a new age of honesty and transparency that the vast majority of the population both want and need.

If we get to a point where blockchain gets the wealthy and powerful to be more accountable and have more visibility over their shady behaviour, ultimately that should deliver a fairer and more transparent society.

Even if banks do return (or stay), hopefully they will return to their original model of helping the local community (and poor) in escaping poverty and accumulating personal wealth without being exploited by others, which ultimately the banks have ended up doing themselves in the competition that this current economic policy has encouraged them to do.
