Looking at the US from the outside, I see all 50 states running themselves quite successfully. OK, some central influence is required for, say, crime that crosses state boundaries.
The US also needs a Military. However, estimates of Federal personnel range from 4 million to 10 million if you include all the contractors. If the states can pretty much run themselves, why do you need another 10 million people on top?
