Negative right: nobody must do something to me.
The right of self-governance is a negative right. I can see how it can be confusing since you can re-phrase anything as either positive or a negative action e.g. "you must stop stealing my stuff so property is a positive right" and "you should not deny my need for healthcare ergo it's a negative right" so here is a trick you can use to distinguish one from another: a negative right will remain even in the absence of all other people while a positive right will disappear in such a case.
So, for this case, the right of self-governance will remain if everyone else disappears since you can still make laws, obey them and enforce them on yourself thus it's a negative right.
