Natural rights are those freedoms and protections we SHOULD have before God/nature/the universe. Natural rights do not self-enshrine themselves into constitutions or legal codes.
If you are deprived of a right, for example the freedom of speech, you still have the natural right to free speech, although you have been rendered incapable of exercising free speech.
Legal rights/privileges are VERY important. The Bill of Rights is an attempt to enshrine Lockean natural rights into legal code as legal rights/privileges. The govt can take them away at any time the people allow them to be taken away. Yet, after they are taken away they are still natural rights.
