Actually, this is all driven by streaming and apps. If the goal is to bill for individual games then the goal is to produce as many great and meaningful games as possible. So for example, under the current system many games are uninteresting or meaningless. Add to that the committee approach to the playoffs (which has ignored losses and wins during the season with a healthy dose of ND gets a hard pass) and you end up with a desire to create an NFL type system, with geographic rivalries and no committee.That's an excellent question, and one I don't have a direct answer for.
On a related note, however, I predict that within a decade there will be certain college football games that will be available only through a streaming service (think Texas/OU, Florida/Georgia, tOSU/Michigan, the conference championships, the playoffs, etc.) and the streaming services will gradually up their rates, because they can.

The NIL will also play a part, and the NCAA is the one organization without the skills to monitor or regulate. 24 to 30 team conference of teams capable or willing to invest and participate is inevitable. Two to four more teams to the SEC and it is over quickly. BIG Ten Network can compete somewhat because many people up north watch sports other than football on the network but a theft from the ACC or Pac does not solve their content problem. It only adds more mouths and less backs. 4 teams from the PAC, ND , two Big Ten teams and Clemson and FSU are still on the table. They all must join together or risk being irrelevant.
FWIW, I suspect other sports will essentially remain in geographic conferences practically speaking.
