The hypothesis that the brain imposes constrains on possible languages is trivially true and the alternative that languages can be free-form is a straw man. That's the problem with universal grammar, depending on who you ask, it is either absurd or trivial. Perhaps there are more sensible formulations of the idea but I have yet to see them.
