The fact is that people are born into society. People who lived before us created a system where rights are protected and, when you reach the age of majority, you have the option of participating in governance either by voting, or running for office or other political action (this is all assuming you live in a Western style democratic republic).
I am not sure where you get the idea that you are being violently coerced into living in civilized society and thereby following the pre-existing laws, simply because you never signed a contract or, equivalently, expressly consenting that you would. Contracts are a legal convenience. A convenience whos very enforcement is dictated by the laws that you rail against for not having explicitly agreed to them. A bit of a chicken and egg problem, wouldn't you agree?
Your argument is absurd. "I didn't agree to have red lights mean 'stop'!", "I didn't agree that murder should be punished!", "I didn't agree that I couldn't build a hog farm on my suburban front lawn!". I mean, come on. What is your alternative to expecting people to live by certain rules that their ancestors through their previous political action put in place? Start from scratch with each new person? How would we tell who agreed to what? There are laws that I don't wholeheartedly agree with either but, for the most part, they seem pretty reasonable. Your 'system' or lack thereof, wouldn't fly in a household much less a nation.
