I think a more nuanced approach, eg the Zack Lystedt law is appropriate until we under stand the science better.
The key part of that law is that athletes must be taken out if they are suspected of a concussion, and they can't play until they are cleared by a qualified professional. Unless and until we find scientific evidence that it is the absolute number of concussions in someone's lifetime, and not back to back concussions without recovery, that cause CTE this seems appropriate.
