Good list and I agree that there are reasons that traditional banks are reluctant to start using blockchains. But for a good discussion I don't think we need to call them corrupt, there are other reasons that the banks are slow. Many industries have problems adapting to new technology, look at the music industry or automotive. I think the banks know that they need to change but they didn't understand the impact of blockchains and they haven't seen technology as their business, their competence was in understanding the traditional financial system. Know they need new competence.
