@Jeffro Your comment about how well intentioned regulation can help or harm a community makes me think of a similar situation but entirely different example. Certain bicycle studies have shown that requiring cyclists to wear helmets actually makes the overall community less safe. You would think that a simple straight forward law to make people wear helmets would be beneficial, but it actually can have the opposite effect: http://americancity.org/magazine/article/putting-a-lid-on-it/ . I see a weird parallel here. Regulation, no matter how well intentioned, can effects far beyond what you intended.
