Sure I do, until I commit a crime deserving of death and Forfeit my right to life. Go fire some bullets at a police car and see how long your 'right to life' lasts. You can voluntarily give up any of your rights, by choice, whenever you like and no one can stop you. Your right to liberty can be given up just as easily if you voluntarily enslave yourself (however informally) to another person. Most liberals gave up their right to be happy long, long ago.
