The obvious thing is, governments don't need their own IP addresses. They can just go to their ISP, and get PA addresses from them, just like any other customer.
So if this is to work at all, the registry has to revoke all IP blocks from all ISPs in the country *where there are any government customers within them*
Basically it's saying: "AfriNIC's policy is that under these circumstances, ISPs must stop providing Internet access to governments; or risk the ISP themselves being cut off from the Internet"
That's going to fly. Not.
