See Steve Krug's book called "Don't Make Me Think".

Of course we should! And let's dry up all the water because people drown too. No but seriously, part way through my post I conceded that if it's used for usability purposes, client-side validation is not a problem. But if someone thinks that it's a security measure, they are mistaken. Until I see that it's more common for people to use client-side validation as a usability tool I'll probably always bring up the fact that it can not be used as a security measure. Chris.
