The length of a law doesn’t reduce its murkiness - in fact it makes it more pronounced. That is why (in the common law systems) there is so much discussing and re-discussing of topics that plenty of other cases already covered, using new approach angles. If you make laws longer and more complex, you only make them serve more those that have the budget to explore all branches of the decision tree.

I mean, sure. Corruption exists. But the that's another issue entirely. Your comment doesn't add to the question of the GP - "does the existence of edge cases make implementing a law extremely difficult?" The answer is no. You could probably outline all the exceptions and applications of such a law in a few pages.
