I never once said that just being nice to women will get you the one you want. What I said is that women connect a lot more with how you make them feel and how you project confidence about yourself and what you have to offer the relationship than how you look but that this is much easier to do off of a dating app, where looks are the first impression and women are so bombarded with interest due to the vastly more numbers of men than women on them that they often use looks to cull the herd.
"Nice guys" who aren't actually nice, just entitled and who think love is a transaction where you put in X and get out Y are nearly always going to finish last. Men who know who they are and what they bring to the table and who treat women like people, and not sex-dispensing machines they will get if they put in the correct "coins" usually do just fine no matter what they look like.
