I am not sure you understand the basis of currency after having read your posts, or have a sound theory on the basis of currency's value. Banks are a system of currency distribution. This whole bank vs. innovation isn't even close enough to reality to even be called apples to oranges.
You are welcome to inform me about what apparently it is that I do not understand. I can then rate and thank your post accordingly.
I had not intended to present the topic as a contrast. In fact, the quote about competition in the OP was meant to make that clear.
The idea proposed was that banks are an example of stability, or firm establishment, therefore not having to do anything about Capitalism, and yet assuring it in it's unstable baby steps with its successful project, and perhaps even serving as an indirect example of innovation, since they relate to and depend on an extensive diversity of businesses and peoples, but do not associate themselves directly with that diversity.
Your post is making no sense to me after having read it 5 times. Socialist countries have banks. Communist countries have banks. I am not sure why you think banks are so closely tied with capitalism. I doubt you could find a country that does not have a bank but they are not all capitalists countries.
