Sounds like you're trolling here, but I'll bite.
The reason for the rules is to level the playing field in college sports. The collegiate game is built around students participating in athletic endeavors, representing the school and building school spirit. The students that participate, although at the upper levels are provided scholarships for their unique talents, are amateurs, and are thusly governed by the rules associated with amateurism. The NCAA membership has adopted amateurism rules to ensure the students' priority remains on obtaining a quality educational experience and that all of the student-athletes are competing equitably. Membership established the process to bring about national uniformity and fairness. All incoming students must be certified as amateurs. As part of maintaining that amateur status, the student-athletes are not allowed:
Contracts with professional teams
salary for participating in athletics
prize mony above actual and necessary expenses
play with professionals
tryouts, practice or competition with a professional team
benefits from an agent or prospective agent
agreement to be represented by an agent
delayed initial full-time collegiate enrollment to participate in organized sports competition
If a student-athlete wants to "get paid," then they can become a professional. Granted, you have to be 3 years removed from HS to be eligible to play in the NFL, but that has nothing to do with the rules affecting amateurism or college football. Those rules are governed by the collective bargaining agreement between the owner's and the players. It's been settled in court by Maurice Clarrett and Mike Williams' case. Is it right that the NFL excludes players from being eligible? Don't know. But that's not the NCAA's problem. If a player wants to play for pay, then there are other avenues, maybe not as lucrative, but there are other options.
There is no question that the NCAA is a biased and damaged organization. The entire sense of amateurism is being warped because of the money involved. But just because the system is approaching the farcical doesn't mean the whole thing needs to be pitched. This isn't a "free market" situation. If you open the flood gates and let the players "get paid," the national championship will go to one of about four schools every year. My guesses are Texas, Oklahoma State, Ohio State, Michigan. If you're going to pay the students to play, why make them students? For that matter, why shouldn't the high school players get paid? What about the middle schoolers on some of the AAU teams?...
...alright, I've lost my steam. I haven't covered everything here, so there are holes to poke at, but you should get the gist of what I'm saying....
