At what point does "College Football" separate from college?

This, to me, is the stumbling block. Realistically, there is no reason for college football players to be required to attend college classes for eligibility to play. I see a point where someone creates a team not associated with any university and demand to be included in the "league", which would attract some of the best players and pay more than any NIL deal. Many baseball players who have no interest in college annually opt for MiLB and turn down full-ride scholarships to top ranked universities. I imagine if that path existed for football and basketball, many players would choose that.
