Because "houserule it till it works" allows and encourages each DM to tailor the rules to suit the specific game-setting-campaign she wants to run; and also allows those tailorings to go off in different directions from the same base chassis.
Nailing it all down hard might suit one table just fine but make the game unplayable for another. I don't think WotC wants to go this route.
I think you might misunderstand what I'm advocating here. I sure as heck don't want "nailed down" rules that make the game unplayable for a group. I want spots where the game doesn't work properly to be fixed so that it does. I'm not asking for anyone's favorite rules to be changed to something terrible. I'm asking that when a rule is widely considered to be bad, incomplete, or confusing to be replaced with something that is widely considered better. Only in cases where the best review of the rule that you can find is "it works fine, I guess, if you ignore most of it or houserule it or if you play by RAW (even if RAW makes for a bad play experience)."
I'm absolutely not talking about changing things that are a matter of opinion or good for one playstyle over another. I think that's the whole point of this thread. Nor do I have anything against houserules that are designed to customize the game to a table's preferences. Those are great. But houserules to patch bad, incomplete, or confusing RAW? We'd be better off with better RAW.
