I guess as long as you don't care if your child is female or male then that's your call.  Not me. I would never want my daughter to cut off her breasts or son have himself castrated and take hormones for the rest of their lives. It makes me feel sick at a visoral level.  That's where I don't see how you can say gender is assigned by society.  If you need surgery and hormones to change who you are then that just can't be right. Are you aware that hundreds of trans people are changing their minds and detransitioning?
