The HUGE political elephant in the server room is that most activities of the House and Senate could be conducted online (votes, committee hearings, etc.). Nobody needs to travel to Washington like it’s 1800 anymore. Of course, this would necessitate our representatives having to stay in their home states amongst their constituents instead of running off to Washington to get away from them. The DC call girls would suffer, too, something awful.
Some things, perhaps, but the majority of the very important or security-related issues and decisions need to be carried out on a face-to-face basis. Vidchat does not work in all cases, not to mention the difficulties when there is a network issue interfering.
