I agree.

If someone wants to do something interesting with protocols, how about making a zero-knowledge [1] protocol wherein the person sending a packet can't see who requested it, nodes which forward it can't see the sender or receiver, and perhaps even the person who requested the packet doesn't know who sent it. Zcash [2] does something like this for tokens; I'd like something that is much more efficient (lower overhead) than Zcash's blockchain-based technique.
