Getting rid of monoculture via transports and cryptography being pluggable (meaning that the resulting system would be fit for sneakernet as well as for some kind of federated relays as well as something Kademlia-based, the point is that the common standard would describe the data structure, not transports and verification and protection).
You sound paranoid but it doesn’t mean you aren’t right, at least to some extent.
