We have a solution for that, we call it an InternetRelay, they are part
and parcel of what we are deploying on cable.  Surprise!

And while your fording the stream with your tanks to
liberate those shackled by RevisionistDemocrats
you accidently crush
ten civilians and your 120mm gun goes off and you take out the town
Hospital.  "I'm sorry, I'm from the government, I'm here to help".  Basically
you can cause more problems than you are solving with your current tac.

I'm not eliminating all hierarchy, I'm arguing (at least) mixed mode,
and of course no renumbering.

If you think the current IP is going to deal with China then you have
lost sight of what are reasonable design goals.

Start again with new white paper.

Don't saddle the current IP with 
totalitarian-administered CIDR to reach that goal.
