People have an inherent right to exist. People have an inherent right to self-determination. People have an inherent right of free association.
But the artificial constructs they create through these rights do not themselves have the same rights, especially given the explicit purpose of these artificial constructs can directly interfere with these inherent rights. We create and destroy these constructs as we need, as we feel appropriate, something we should not do with people.
This means they do not and cannot have the same rights, they exist solely to serve a purpose, and in fact should be eliminated when that purpose is perverted or when that purpose causes harm to actual humans.
Israel, a settler-colonial construct explicitly designed to create an ethnostate for the domination of all other races by the nebulously defined Jewish ethnicity, does not have a right to exist. The people of Israel? Sure. But they give up that right as they take it away from others. The state itself? Absolutely not. Not only does it not have a right to exist, it is the moral imperative of all free peoples to ensure that it cannot continue to exist given the immense harm it inherently requires.
