If you're asking about natural rights, they are rights that we all possess. And all rights are property rights. Let me explain. Natural rights are derived from the principle of self-ownership. First, you own your body and your mind because you have exclusive control over them. You were the first person to have that control and without mind-control devices, you can't surrender that control to someone else. Anyone to "take" control of your body without your consent would be violating your rights since you had ownership of your mind and body from the start and did not agree to give it away. Accepting that you own yourself, you also own the things that you either appropriate from nature that no one else owned first, or that you received in a voluntary exchange with another person. Your natural rights, therefore, are the right to be free of coercion from others against your person and your property. All rights are property rights. Where do they come from? They are just a concept and don't really exist, but I would argue that 99% of people agree that you have them, even if they say they don't agree. If you ripped the shirt off of their back or kicked them out of their house, they would say you stole from them. Even if a communist wouldn't just say, "well, we all own it together so I can't complain!". Likewise, most people agree that harming other people, except in self-defense or in the defense of others, is wrong. Some people don't agree with that, e.g., sociopaths, which is why we own guns and put those creatures into cages, so that they don't hurt anyone else. So basically, these natural rights come from a mutual agreement among the overwhelming majority of people who want to live peaceful lives, not harming other people and not taking or destroying their stuff. When I say "mutual agreement", I am not referring to any kind of social contract. There is none. That mutual agreement is just inherent to the way we, as social animals, normally operate.
