The drawback of that approach though is that due to the sudden slowing down of information transmission (flawed and tinted - and in some cases, perverted or intentionally mis-told - as it was), people would also be overly insulated and presumably ignorant about the current happenings of the world (bad or negative as they were). We'd be less inclined to make decisions that would benefit society and other members of our species, because perspective would be both narrowed to only what we can see, hear, or encounter locally, and those decisions we'd make would be poorly informed due to the lack of bigger-picture details.
I think what's missing (or what's being lost over time) is the ability to discern between fact and opinion, and the ability to separate objective from bias. Critical thinking is perhaps what's becoming lacking as time goes on, and I'm not sure that removing the primary conduits of information transmission would necessarily fix that.
