LuckySpeaking from the perspective of someone with brain damage, I find arguments that rights should be restricted on the basis of whether or not our brains are "fully developed" really frightening actually.
Like -- is my brain "fully developed" right now? Am I capable of making my own decisions? Should I have to get permission for my next tattoo, given the number of concussions I've had?
And tbh I kinda hate framing this as a personal issue as opposed to a general issue, as though you personally, yes you, couldn't be labelled incompetent at any moment. Do *you* have a "fully developed" brain? What if someone decides you don't?
