If you are an individual who has a vote but not enough vested interest to fund a lobbying effort for expected positive ROI, loopholes are definitely a bug. If you are a corporation that wants to undermine regulation by pulling purse-strings rather than by defeating regulation attempts in the arena of public opinion, loopholes are definitely a feature. However, a corporation that pulls the purse-strings to subvert a bill makes itself morally culpable in the bill's intentional inadequacy. You seem awfully sure that this isn't what happened with the car size loophole. Why?
