If you're framing this in terms of "practical" rights, sure. You can do what society allows (or rather, face consequences for what society will not allow.) But I think many of us might disagree that "natural" rights don't exist in a society. They may be unrecognized and disenfranchised rights, but that doesn't mean they don't exist....In any society there is no such thing as natural rights or god given rights. Only rights that society allows. How society is structured and and its values determines what those are....
Admittedly we don't live in a vacuum. Our actions and consequences are shaped by the company we keep. Society is a (more or less) organized set of mores and consequences for failing to adhere to those norms. But just because someone denies the existence of a dog just because they don't allow any in their house doesn't mean the dog ceases to exist.
