I have discussed this with you before, and you are incapable of hearing or understanding, but for the benefit of others so that they will not be confused by you.
Participation in NCAA football is voluntary. In all walks of life, you can voluntarily join an organization, employment or what have you, and become subject to their rules. The NCAA previously had rules against NIL. The reason those rules are no longer enforceable is because it has been ruled that the NCAA as formerly organized was a monopoly, in violation of the Antitrust laws. The 9-0 decision by the Supreme Court was simply affirming that the NCAA as organized violated Antitrust. Antitrust is a law passed by Congress. Congress is free to change its own laws. If Congress granted the NCAA (or some replacement government body an antitrust exemption, for example, let's say the exemption was granted based on 50% revenue sharing with student athletes). If 50% of the revenue was paid to student athletes, then at that point the NCAA would be in the safe harbor and would no longer be violating Antitrust. In essence, Congress would have said "we don't care that you are a monopoly, provided that you follow these rules, i.e. revenue sharing, etc.". If the NCAA complies, it can then turn around make rules based on voluntary participation, i.e. if you want to play college athletics, you have to agree to these rules, those rules can include regulation of transfers and NIL. A 13th Amendment challenge is baloney. Even the Supreme Court that you are so proud of ruling 9-0, said in that ruling that Congress could change the law and do what it wanted.
