> Just because you are in your own network does not mean you are isolated.

You literally described isolated networks. To the point where you had to do an "even though" to try and get yourself out of your logical hole. Do you understand how words work?

The only reason current social networks work is because they allow people from all over the world. You can get a reddit meme on Facebook because someone on Reddit is also on Facebook. If each nation had its own isolated social network only for its own citizens, how, exactly, would someone copy and paste information either from a network they don't have access to (a Turkish person trying to crosspost from US Twitter) or vice versa?
