You're a team player; nothing great has ever been accomplished with just one person. Anyone who says otherwise is probably a not very nice person, and not someone who you feel the need to be associated with. You make friends for life, and you take those relationships very seriously. Like, blood oath seriously.
There is nothing that has been invented that we cannot live without. Because, for something to be invented we've had to not have had it before. People sure would piss and moan though if the car was taken away....to answer your question.
In my opinion a society without laws is a society in a state of chaos. A state without laws and government would be anarchy. By definition anarchy is a state of disorder due to the absence or recognition of an authority figure. Life without some type of rules to control us would literally be a state of disorder. We are all human beings, and by human nature we have flaws. If these flaws are not controlled in some way, they can get out of hand and wreak havoc upon a person and the people around him.
