Not signing the contract simply means having no right to the protections that it affords. I have no responsibility to treat you with respect if you don't go out and vaccinate yourself. I have no responsibility to entertain traditions that you value, if you don't value the traditions of others.

You have attributed a loss of liberty to it, from the comment that you are replying to:

> You are free, of course, to not "sign" that contract - but that means that those who have are not obligated to apply it to you.

Participate in the social contract, or don't, your choice.
