I think you are conflating two unrelated distinct things in a very dangerous way. A book is at best a tool to influence your decision making. A physical object (like arsenic) is something that is acquired after you have gone through a decision making process. Misrepresentation in physical space causes people to misexecute possibly sound plans. Misrepresentations in idea space cause unsound plans to be made. I think regulations that prevent bad executions of sound ideas are OK (and desirable), this rules out things like people busing mislabeled arsenic. Regulations that try to protect people from bad ideas are misplaced idealism and tend to end very very poorly for the societies involved.
