A true national xc championship would simply invite the large school team champ from each state and limit each team to five runners. Run it the second or third weekend in November at a place like Bloomington, Indiana or the Farm at KU. 250 runners, every runner scores. Simple and no need to compete with Footlocker in terms of naming an individual champ.
Your logic is a bit flawed here. In some states, the large division winner is not always the best team to represent that state. And in some states, the winner of any of the top three divisions is better than the all-time best in some other states. In a large state like California or New York, or just a deep state, the best team in that state might be in the second largest division, and they just might happen to be the best in the country - and oops, they don't even get a chance to run? That would be bad.
The qualification process also requires teams to keep training and continue to "earn" their birth in a national championship meet. Not all states conclude at the same time, so it is possible that some of the states that finish nearly mid-October, with a locked in birth, might perform terrible at nationals because they really didn't have to train between then and nationals. That might sound ridiculous, but if your team has winter sport athletes, the pressure for them to start their winter sport season immediately after the state meet concludes is high. You'd see some of these athletes do that, barely train, and run terribly at nationals. At least with the qualification process, you assure that those at nationals will have been training long enough not to embarrass themselves at nationals.
