One may become angry, but modern society cannot permit fighting. In many situations it does not even permit verbal aggression. When going somewhere one may be in a hurry, or one may be in a mood to travel slowly, but one generally has no choice but to move with the flow of traffic and obey the traffic signals. One may want to do one's work in a different way, but usually one can work only according to the rules laid down by one's employer. Most of these regulations cannot be dispensed with, because they are necessary for the functioning of industrial society.
Modern society is in certain respects extremely permissive.
In matters that are irrelevant to the functioning of the system we can generally do what we please. Behavior is regulated not only through explicit rules and not only by the government. Control is often exercised through indirect coercion or through psychological pressure or manipulation, and by organizations other than the government, or by the system as a whole. For instance, the content of entertainment programming is a powerful form of propaganda. Legally there is nothing to prevent us from going to live in the wild like primitive people or from going into business for ourselves.
