If you want to lower yourself to the level of an animal, please feel free to do so. Of course there are examples of animals doing such things in a minor way, but it pales into insignificance compared to humans. Your example of what women do, is just that, an example. There are exmaples of everything, even men that you would consider to be ugly having wonderful relationships with women who aren't just with them for their money or power. Having said all this, okay, so let's agree that you're an ugly specimen of a man - so now what? Does that mean you can't have a fulfilling meaningful and happy life? Of course not, because many in such a situation have managed it.
I am not lowering myself, I am assuming reality as it is.
We have evolved, other animals evolved too.
I think what makes the human space typical is that it is so versatile, we don't have the sharpest vision, nor are our other senses ever the best, but we did learn to adapt.
I didn't say that every woman who is with an ugly man is only there because of financial stability or for the power, but face it, the most beautiful women are rarely with ugly, poor men.
Can the rest of us have a good life?
Of course, but if we continue to try to get the most beautiful women, I'm afraid they will always be out of our reach, and it might make us very unhappy.
PS: I don't consider myself ugly, but I don't have a six pack either, I think I'm pretty average, not ugly but not fantastically good looking either.
Any problems I have I don't think are really related to how I look.
