I get the intent of what you're saying, but the reality is there are definitely "righter" and "wronger" ways to play. Music is incredibly mathematical, and the piano even more so. Written music provides input and queues to things like phrasing, fingering and the patterns that are often harder to decipher by ear. The true beauty to me is that we can use rules and technique to produce something that sounds so organic and pure. That's probably what also drives my deep love of computers and software.
