Society affirms our rights to all of these things. You, a member of society, are affirming them right now and many others agree with you. Our (The US's) legal system, on the other hand, doesn't affirm any of these rights. That's because, as others have mentioned, our rights are almost all negative. Proscribe things that the government and other institutions could do to you. The "right to life" is a line from our declaration of independence. Which is, legal speaking, just some nice words someone once wrote, it's not something that will compel a court to rule in your favor. Courts, despite what you say, are actually quite logical on this matter. The right to life is completely illogical, how can you have a right to something which, by it's very nature you must eventually lose?
