@ rlumley: "I should make them. I should make all decisions for myself."
YOU should decide what rights YOU have? You do realise that that's completely unworkable?
Rights create corresponding duties. For example, assuming I have a right not to be tortured, this means that everyone else has a duty not to torture me. If it is established that I have a right to clean, safe drinking water, then whoever is responsible for the water supply has a duty towards me, to ensure that the water is clean and safe. And so on.
If YOU decide what your rights are, then you are imposing duties on others without their consent. For basic rights like the right not to be tortured, which I just mentioned, this is not too problematic. But what if you decide you have the right to walk around in public in the nude? If this right is valid, then everyone else has a duty to allow you to go around naked. Some people may object to this - they may consider your behaviour obscene, and may feel that they have a right not to be subjected to your obscene behaviour. Both sides claim a right in this case, but only one side's right can be upheld.
So you can't just say "I should make all decisions for myself" when it comes to deciding what rights everyone has. This leads to chaos where everyone claims various different "rights", but no-one's right claims can be legitimately upheld. In this scenario, your "rights" are meaninless.
This is one of the many reasons we need a legal system and an organised government to administer it.
