Would you still transition if society treated you as the correct gender from the start?

I promise I am not a reactionary, but I am somewhat uneducated on the subject so I might say something offensive accidentally, sorry in advance about that.

So, does gender dysphoria stem from a disconnect between the body and some "gender socialization" function of the brain, which could be solved by getting socialized and treated by everyone as the correct gender from the start, or something that stems from a disconnect between the brain and the actual body parts and hormones, so the transition is needed to alleviate that, or both?
