The system you have today is might makes right. If your government was overthrown by a foreign country and replaced, the only difference would be you would temporarily think the new government lacked legitimacy. But pretty soon you'd accept it as the new legitimate authority. This is your cognitive dissonance helping you cope with your submission to this illegitimate authority.
In most cases it is better for the powerful to not take everything from the weak. You want to incentivize them to create more for your to control/take, but never let them keep enough to challenge you.
An actual "social contract" would imply consent and the option to opt-out. But I will literally be thrown in a cage with rapists and murderers if I opt-out. That is the opposite of consent. What you call the social contract is nothing but top-down violent coercion.
