I see some disagreement with you, but I am somewhat of the opinion that I agree (though I don't think it's a great "common user" solution.)

ScriptSafe is running and I allow some sites, trust a few domains, and the rest get, at best, temporary access to run local JavaScript if specific content I want isn't loading. I get the feeling the majority of sites don't even function without JavaScript at this point, and some intertwine their ad system with other "necessary" JavaScript, so it's tough to surf the web without some hassle.

I don't think this is a perfect or even passable long-term mainstream solution.
