Right! People usually accept having a dictatorship implicitly as described by the concept of the social contract, or because they are averse to being killed!
You might look up the definition of "social contract", which is just a description of various social structures, and often not a recommendation at all. Of course, some people do like the concept of a "social contract" whereby the people are controlled by a King or Queen. The ones who approve are the King or Queen and, of course they know what's best for everyone else, or else.
Having pointless and/or evil rules is a definite consequence of organizing a society of millions (only millions?) of individuals, to be sure. A rule that pi = 3.0 is still never going to be practical to enforce.
