Social Contract?

Some people argue that there is a social contract where we all agreed to certain things. I think some people do the same thing with natural law. They make wild claims about what is in the social contract, and claim that we are implicitly agreeing to it by living here or something. Well if you can translate this guy's writing into English, he actually tells me that I can go to city hall and get a copy of the social contract.

Of course, he couldn't be consistent with his demand that I support police while he opposes abortion, so he seemed to give up that argument.
