Not true. You are forgetting the peer to peer transaction system. Which means, I can do business with any other person without the need of a middleman.
We can do business with cash, assets or any other way, so banks are not needed. Sure, they make things easier but they are not needed
P2p transactions do exist, but only a very low percentage of bitcoin adopters use this negotiation method to deal with bitcoin. Without middlemen (exchanges and banks) most people wouldn't be able to transact bitcoin anymore, and I include myself here, because I don't know trustful people who I could buy or sell bitcoins directly, since there are no guarantees.
Moreover, middlemen are good to keep the market competitive, what means customers have access to cheaper fees when sending, buying or selling bitcoins. If we had only p2p transactions, I guess some people would get skilled really fast on this field and charge expensive fees from customers, as it would be harder to find verified legit people willing to make business.
