My point has been throughout, that is exactly what is happening. You can look throughout history and find that this is true. I also pointed out that as society progresses, it almost always works towards a less restrictive list than before (not always, but almost).
This is only true where no social contract exists, in autocracies.
In an autocracy, the person holding sovereignty (monarch, dictator etc) creates a list of what they deem will be allowed and exercises vengence if that list is transgressed.
Where a social contract exists, and the individual holds their own sovereignty, an individual agrees to suspend certain freedoms, in exchange for their respective freedoms. It is in this that rights are seperated from simply the power of will. I still have the freedom (ie will and capacity) to, say, kill, but it isn't the vengence of society that prevents me from doing so, but an uncodified (and to a degree codified) contractual agreement that I will not kill in the exchange for the right not to be killed.
As to whether societies tend to move towards moving the contract to allow more freedom, I'd say it cycles. Society goes through a period of liberalism, and then panics that we have too much freedom, cycles back into slightly more authoritarian, realises it has too little freedom and cycles back....
