This isn’t an argument, it’s a fact. The only way to not be part of the social contract is to remove yourself from society, including all of societies infrastructure. You are obligated to support and work within the rules of the society you are a part of. If you object on moral reasons then you can make your attempts to change your society or which society you are part of through whatever means you have access to.
I see your problem.
You don’t believe people when they tell you who they are. You imagine their actions and their beliefs to be separate from the individual even though they are the beliefs and actions of the individual. Your idealism doesn’t reflect reality.
