Your point is invalid. The kinds of students only partly determine the pass/fail rate. The professor is also a factor, and perhaps the major one. Not all professors are the same; some are better (or harder) than others, and it's always been that way, because professors are only human (at least until AI takes over education completely). A grading curve (e.g. a mandatory 7% D/F rate) guards against grade inflation by professors, which is a far more common occurrence than some hypothetical class filled with nothing but geniuses.
Many of the top universities grade on a curve for two reasons: 1) to guard against grade inflation, and 2) to foster competition for grades. That second reason in particular irks some people, who think it might be unfair. Yes, you could get an F despite getting 90% on every exam and homework if everyone else gets 100%. On the other hand, you could get an A despite getting only 60% of all possible points if no one else could top 40%. Overall it tends to even out. Competing for grades tends to bring out the best in students who want a good grade---you won't be able to just coast to an A, you're going to have to outperform other students. Is that unfair? Life is unfair. Students should be prepared for the type of competition they'll face in the real world.
