It's precisely the reason you give for severe consequences that concerns me. If I thought all-sex-all-the-time actually led to human happiness, I wouldn't have an issue with it. But it doesn't work. In my experience, the people who regularly throw themselves into sex with the nearest warm body end up feeling emptiness and meaninglessness. Worse, however, the ones who fall into this pattern while simultaneously pretending to maintain a stable family life create intense destruction in those around them. I am quite concerned that the offspring of promiscuous parents are damaged for life. The research is clear: kids growing up in stable monogamous heterosexual relationships grow up happier and more stable than those in other environments. Do we want a more happy and stable future generation or not?
