In the real world, ethics and morality are too complicated to expect everything to be codified in explicit laws. Laws are mainly concerned with those aspects of society and relationships that require intervention of the state (and what fits into that category is quite debatable as well -- libertarians think it's very narrow, and anarchists think it's the empty set). We don't have laws defining polite versus rude behavior, everyone just knows them.
A game, on the other hand, is generally considered a microcosm whose rules CAN be summed up concisely. So we write Laws with the intent that they cover all the bases. However, while they obviously come closer than the laws of regular society, it's not clear that they succeed 100%. Consider that every 2-3 months the editorial in The Bridge World is about dumping and whether it's legal/ethical. The conclusion is usually that it's legal, and that makes it ethical because the Laws define the ethics of the game, but it still "smells" wrong.
And then there's Law 74, which makes reference to courtesy, annoyance, and embarrassment, which are quite subjective.
And while we'd like to think that when we're in this microcosm we can divorce ourselves from ordinary social conventions, we're not automatons. Many people feel guilty taking advantage of quirks and loopholes in the laws. World champions have admitted to letting opponents take back an inadvertent card, rather than calling the TD and taking advantage of the penalty card laws; they want to win through normal cardplay, not through the legal system. Their personal ethics trump their need to play by the letter of the law. However, this is entirely personal for them, they don't consider anyone else wrong for playing strictly by the rules.
