What is a use case which most people support, but which is prevented by government?
That girl who wants to provide access to subscription science articles is one example.
Your false assumption behind this conspiracy theory is that a paywall would have been created by any government for the purpose of displacing poor countries, making the rich richer and the poor poorer. But this is ridiculous. Paywalls are simply services to generate revenue for digital publications. It's the same as online shopping or digital distribution. Anarchy would just mean freeing up all local or digital stores for plundering, and welcome back to the Stone Age!
How long would it take a developer to make a clone of Namecoin, but adapt all of the features to that specific use and maintain all the positive features of the original nmc like the high hash rate from merged mining, along with each wallet having the option to interact with the other chain, like a bitcoin cash but not entirely divergent?
What do you mean with "interact with the other chain"? Cross-chain trades? I wouldn't consider this as a usefull goal of a blockchain DNS. Namecoin can be mined together with all SHA 256 encoded currencies by the way, and a non-negligible percentage is mined on the Bitcoin Cash chain. Blockchain domains have their main use cases for projects with problems of seized domains through restrictive dictatorships. It's not the goal of the Namecoin project to overrule and to circumvent the applicable law of civilized states (what, by the way, was one of the reasons that the .bit domain resolution through the OpenNIC project has been dropped).
