Thank goodness, NCAA has been a blight on collegiate education for decades. The end of NCAA would be good for students, good for athletes, good for athletics, and good for colleges and universities. If most of what an organization does is harm, then absolutely that organization shouldn't exist.

I’m curious how ending the NCAA would be good for all those stakeholders.

The NCAA's monetary and administrative requirements distract from the educational mission of colleges. Ending that distraction would be good for students and colleges. NCAA's conservative tendencies and commercial interests hurt athletes directly as documented extensively on this page, and as often attested by the athletes themselves.
