I think the point is that she was willing to do terrible things like commit treason for money. it's fine to lust after money, but killing people and ruining lives for money is not okay, and i think that is what the author is getting at
The title said “does not BLINDLY follow money”, instead of “does not follow money”, imo that alone already delivered the message that they still can lust after money, but when searching for it, one should make rational choices instead of justifying all actions to obtain it. It’s a suitable title for FL who did every dirty work in her past life to get money and now wished to change in current timeline.
I think it's about not making your entire life only about money. In her case, money was so important to the point where she would take any job as long as it paid her good money. In the end, her blind desire for money prevented her from being able to notice that her commandor was taking advantage of that desire that she had. After reincarnating, she also realized that she lost a lot of good friends. Money is still hella important, but it's risky to make your entire life about it to the degree where you can not notice when you'rr being fucked over or losing people in your life that are actually very good people to have
What sort of bs message is the author tryna sell? Don't lust after money? Sure, easy to say if you're already stable but she's broke, with no one to financially depend on. There's nothing wrong with wanting money, only if you hurt ppl/yourself unnecessarily for it.
