TLDR; His thesis is only a thesis without a code proof of concept/implementation. Knowing what's bad is harder than stopping it.

His thesis is interesting and makes sense, but I don't see it having a practical implementation that would not be better serve with just robust key management. Because Bitcoin depends on the ownership/control of private keys to use, that is the core security protocol. You can have asymmetric cryptography using private/public key pairs without having Bitcoin involved. I **do** see widespread use and knowledge growing around handling of these keys which may lead to some unique application int he cyber security space. Having hard money you can't fuck with though, would be immensely helpful for a nation state, but don't think that's the DoD's lane.

Additionally, cyber security's biggest challenge is identifying what is a "bad" action compared to allowable actions. Stopping bad actions is pretty trivial, but knowing what to stop is hard. Again, I can't see how involving bitcoin shifts this paradigm at all.
