A broad range of policies sends the message that people are too dumb to make reasonable decisions on their own. There are undoubtedly people who might benefit from advice, or from sensible rules, or from being protected from themselves. But policies that attempt to protect people from themselves risk reducing self-reliance more generally.
Laws against false and misleading advertising are one example. Some business do attempt to swindle their customers. But prohibiting false and misleading advertising gives people an excuse not to worry about this issue. Government enforcement of the ban is highly imperfect, however, so many questionable claims occur every day. Thus unless people use common sense they can easily be misled despite existing law.
Numerous other policies also reduce self-reliance: prohibitions on “bad stuff” like drugs; nutritional guidelines; regulation of decency content on television; safety regulation; food labeling laws; and licensure restrictions for doctors and lawyers.
Government intervention therefore promotes the false message that people do not need to think for themselves because the government has taken care of it. No matter how large government becomes, however, it cannot be everywhere or make every decision. So unless people use common sense, or rely on private institutions that provide good rules of thumb, they will make many bad decisions or be taken advantage of in many situations.
