Hello rage-flag boy,
Indeed the social contract is ridiculous but you can renounce your U.S Citizenship and go live in Liberland, an an-cap nation in Europe with absolutely no problem. 2 friends of mine did just that. Another one lives now in Kuwait and another in Sweden. They accepted all of them them with no problem after filing the form for political asylum. It's time consuming but it can be done.
You can't expect others to give up their dellusions just because you have a different set of morality in a place where you were borned much later on. Simply, it won't happen. Tradition is a very strong influence on someone. They don't care about logical fallacies. Logic gets you from A to B when you define the constituents of an argument. For example "I love my country ---> therefore I follow its rules". Go tell a Murica man that he is doing an "appeal to emotion" argument. Simply, this college-tier arguments are just intellectual jerk circle that belong only in safe spaces like college campuses.
This is why doing (like living in Liberland) is much more effective than talking — especially when you do it in the most philopolemical nation of this planet, the US-of-f'in-A. It's like preaching to cannibals in the Amazon that human consumption is wrong and that it violates individual rights. You might be correct in your western-anarcho-voluntaryist glass bubble, but they simply don't care.
Remember. Morality is subjective. This is why you shouldn't bother with other people's morality whether they are stoning people in the street, burning women along their husbands (india), drowing young girls (china), executing people (usa), etc etc. If your way of life is more efficient in liberland then more people will join constituting USA or any other "social contract" nation obsolete. In this way you become a voluntaryist (like moi), minus the whining.
PS: Here is how voluntaryism is done
