The general idea that women not being attracted to men who are attracted to them is just some arbitrary wrongness in the universe that any sensible man should try to get the women to ignore.

Fixing the man (as opposed to confusing the woman) seems like a good intervention, if it's possible to a sufficient extent. The difficulty is that behavior and appearance are important aspects of a person, so fixing someone might involve fixing their behavior and appearance, which will be superficially similar to changing their behavior and appearance with the goal of confusion/deception. This apparently inescapable superficial similarity opens benevolent self-improvement in this area to the charge of deception, and it looks like it's often hard for both sides to avoid mixing up the categories.
