Okay, let's try to be a tad more precise. There is a subtle but important difference between: A) "There is no valid reason for 66nat" and B) "There are obvious ways to solve the problems that people want to solve with 66nat that are both easier to understand and technically superior" The two statements should have equivalent truth values, but the second one is more illuminating. It follows that if we want people to avoid using 66nat, we need to (a) identify or provide technically superior solutions that are easy to understand and (b) make them obvious to people.
