I don't understand why you'd trust a corporation more than Congress when it comes to how the tax code should work. If we all pay what we think we should owe, rather than what the rules tell us we actually owe, that would lead to chaos.

"If we all behaved the way corporations do" doesn't really mean anything. Corporations are people. It would be much more accurate to say "If all people behaved like the people who work at Apple, the world would be a worse place," but I don't think that's defensible at all.

If it does become a social norm to obey the law you wish Congress passed, instead of the law they actually passed, you're subsidizing people who ignore this norm. I wouldn't want to live in a world where RIMM out-competes Apple because Apple scrupulously follows good, imaginary rules, and RIMM scrupulously follows actual rules instead. This would all be a lot less meaningful if the US had lower corporate tax rates, but ours are effectively the highest in the world. Since the corporate tax rate is also the subsidy for hiding a given amount of income, it's no wonder that we lead the world in tax avoidance, too.
