By binding I simply mean that

By binding I simply mean that the person making the moral demand thinks that others are bound to behave that way in order to be moral. If a morality is objectively true, then such behavior would be binding for someone to be moral.

It's easy to make a valid argument against specific theories of property rights, that's why the subject is widely debated. The theory popularized in NAP is not widely accepted.
