Your assessment fails to understand Bitcoin's core value proposition, which is that it's highly resistant to centralized control and thus is guaranteed to remain a permissionless (open) network and a fungible currency. If a centralized Bitcoin did somehow manage to gain worldwide adoption, it would be indistinguishable from the current international banking system. In practice, a distributed blockchain that is centrally controlled is no different than a centralized data center like those that run VisaNet. It would have all of the same shortcomings and vulnerabilities, owing to its centralization. What you propose is totally impractical in any case. For example, who's going to regulate Kenyans' use of Bitcoin? Every country has its own regulatory regime and no country is going to embrace regulations imposed by a different jurisdiction.
