If we in American did have a government then the world would be so different and everything would be crazy.   There would be no courts no cops firefighters there would be fighting and killing non stop because there's no one to stop them.  Even though stuff like that happens with a government already it would be a 100 times worst if there was no cops.  An if we were to have no firefighters house business and more would just burn to the ground.  It would kind be like how the movie Purge would be people would lock down there house get fire arms and weapons and there would be 1000 to millions of people dying all the time.
                There you be no high way department or services  to help with anything wrong.  If there was no highway department the roads and  highways would but nothing or even dirt and there would be no one to keep up with them.  If there was a crash or accident the there would be no one there to save you to get you to safety or to pull you out of the car.  During the winter there would be no plowing crews to keep the roads safe and clean.  There would be no banks to keep money and gold in a locked up place .  There would by no  car company's no  so it would by hard to get around.  There would be no jails so from rapers to murders would just be running the streets with nothing to get caught for.
                 I think that human made this organized government so that are country of the United States   because they didn't want to see fires just go crazy and people to just kill and get away with it.  The made it so we had a president so we had a leader and someone to follow to keep are country going.  They made the different branches of the government so just one part didn't get the blunt of everything and everything split up
