To be clear, I don't think they're less important. I think they're unenforced. But in my experience most people don't seem to really believe in the rights in the DoI if it would cost them anything. For instance, just the right to life would _definitely_ include a right to water, which is an example given elsewhere.
There's an inalienable right to water to the extent that a government would be tyrannical because people didn't have water. I can imagine a few different scenarios where that would be the case.
The "right to life" was more broadly talking about who owns a life (the individual, nature's creator, not the government). It wasn't talking about the right to be free of all death.
