I can't tell if you're trolling or not. I really hope you are because there is little to no truth in what you wrote here. Independant states are integral. Pick up any 6th grade textbook on the subject for the awesome "deets".
The original 13 colonies literally predated the fed. States weren't created for the convenience of the fed, it was the other way around.
The People predated the States. People weren't created for the convenience of the States, it was the other way around. Now the States are just another layer of bureaucracy that people have to deal with, and I argue that giving people a larger voice in both local and national politics makes more sense than having these artificial State constructs get in the way.
