I agree with your assessment, but I think it's a good thing. It's basically yin-yang balance. When women go too much in the direction of social progressivism, men inevitably have to balance things out by bringing back the older value system of physical prowess. From my experiences, steroids and psychedelics almost have opposite yet synergistic effects on the mind. It's the balance of creativity and rational action, or as Nietzsche puts it, Dionysian vs Apollonian. Steroids is the triumph of the Apollonian ideal. You get a sense of order, accomplishment, and clarity from lifting weights. Yes attracting women is a bonus, but it is much more like playing a RPG video game than a means to a reproductive end. 

In the old days, a few men lived the lives of the archetype hero who goes through the hero's journey to bring value back from chaos. Nowadays, society has been democratized, so now everyone seeks that experience, some through movies, some through video games, some through bodybuilding. The delusion is in the biased mental focus. It's no different from the nerd thinking that he deserves all the women because he has memorized facts that women don't actually care about. Just because you enjoy a particular activity or way of thinking doesn't mean that you deserve the appreciation of others. This is true for everyone... bodybuilders are simply the most externally visible.

This is why I don't have a problem with bodybuilders. Many of my good friends are bodybuilders and I also know plenty of liars and insecure scammers in the community as well. It all depends on if you feel entitled or arrogant about your achievements.
