The NoScript approach is dumb because it easily supports temporary and permanent white-listing of sites, which is agreeable to many (but still problematic depending on what your risk profile).
With NoScript’s current approach, you get ruined when your JavaScript-free-optimized starts sending you nasty JavaScript.
Tech-literate people use JavaScript.enabled=false in about:config.
