Long ago I overheard a game being proposed where one of the players is not allowed to resign. As someone promptly mentioned, in real life a player could 'resign' by simply getting up and walking away from the game. Nothing can really avoid that, unless somehow said player suffers some sort of penalty, say in a rated tournament situation, or at the least suffers a social stigma of some sort instead.
