Ha, someone might actually get offended by that comment!
And really, many people rely on foreign and top level solutions. I know loads of people who use Tokelau-aliases for their websites. And Niue-servers to host them. To put it frankly, I'm offended by this comment. However I understand how you think, and it's perfectly fine wanting to increase one's security.
But a solution like this would simply not work. Especially not if everyone started using Windows' and browser's which block foreign content. Multimillions of dollars will be lost if the world-wide-web stopped being world-wide. Foreign people would stop learning things from YouTube, foreign people would not be able to chat with friends on Skype, MSN or Facebook, foreign people would sieze developing. And no good can come of this, you know...
