Apparently you haven't figured out yet that these two are partners. The government restrictions are needed in order to allow other players to perform correlation tracking and deducing your identity.

This is untrue in the light of what I said above. The proposed scheme lacks any proof of immunity against tracking and deducing identity. I haven't seen anything like a proof being discussed anywhere while an honestly implemented scheme would require a long and well publicized discussion of the means of protection to make sure it cannot be abused for political reasons.

The lack of such a discussion is actually a proof that the purpose of the proposed scheme is precisely abuse.
