While that might technically be true on some level, ask yourself if the average student would do well if they started with Rudin's Principles of Mathematical Analysis in 11th or 12th grade having taken absolutely no calculus prior to it. There's a reason most universities require students to have completed the entire calculus sequence and often even a special "introduction to proofs" class before exposing them to a book like Rudin's.
