I would not be so quick to call people brainless. Generally speaking, I would prefer that congressmen be specific with their legislation and, like a good doctor, try to first do no harm or as little harm as possible and address the problem before them specifically without causing unintended consequences.

As I wrote in a previous comment on this thread I am sure the congressman that passed the law discussed the issue with farmers and ranchers producing all traded commodities and the ones that were not growing onions did not think there was a significant risk of a corner and they preferred to have their goods traded.

Although I do agree with you that privacy protections should be broader. As far as Megan’s law I am sure you realize that it is intended to protect everyone from sex criminals not just people named Megan.
