The first question we need to ask you is what Norwood are you? I'm guessing around NW2?
Edit: Of course he is a good-looking NW2/3, shaved by choice. Wait until you're bald and all that..
Unfortunately the effect doesn't work linearly, and we can't choose what we are attracted to. Some guys go from a 7 to a 2 bald. For someone like that, the quality of women you will be able to attract would be very low, with great defects in both body and soul. As Wolf Pack says, most couples are looks-matched and while you will find exceptions to this it holds true as a trend on average. So as a 2 you won't be able to hope for much more than a 2 or a 3, on average.
Winston Churchill was an exceptional person, and furthermore he belongs to another, less image-conscious era that did not have Facebook or Instagram. Most of us are average, above or below in some cases, and live in an exceptionally image-focused point in time. I will not be doing any great deeds in my life, it's too late for that, and can't rely on them to impart value onto my person.
Our lives do have meaning beyond our appearance but a good one helps your life in too many ways to count. Even in those areas of life that you would think are mainly meritocratic, like professional life. I have seen it close hand as someone who went from barely caring about my appearance to adopting a highly polished look and style. The quality of life is not comparable. Baldness will take me back to my starting point and worse.
