I’m all about changing opinions, if you have any data that supports breasts not being viewed sexually at puberty due to societal structure, I’m all ears.
It’s dangerous to let these massive corporations play scientist with society if you ask me. A better method is to reinforce it via parenting. You’re fighting an uphill battle when all of the policies enacted simply get parental controlled away.
On another note, humans are the only mammals with enlarged breast before any egg has been fertilized. We’ve evolved to show them off for some reason, and that points to deeper biological underpinnings than purely society. It is entirely possible that you won’t be able to free breast without unavoidable consequences that won’t improve.
