You heard of New IP? The Huawei/Chinese plan to reform the Internet that keeps getting criticized for a variety of reasons. I haven't had the times to read the proposals proper, but the stuff about build trust directly into the network seems like it could solve this problem, at a price.

> Having security and trust be “intrinsic” to the network will require core layers to carry metadata about the users, applications and services being transported. If users need to register in order to have packets sent to their destination, the result is that network operators, and those who license the operators, can remove individual users’ access at any time.
